Cali & Co. Mystery Block 12 + Finishing Instructions

We’ve done it friends…we’ve made it to the final block of our Cali & Co. Mystery BOM. What a fun year of sewing it has been.

This is the last block that you need to complete for the quilt.
You can download block 12 here.

Our last Coriander Quilts video of the this year includes a block tutorial for this final block as well as a talk through of the finishing instructions.
You can download the finishing instructions here.
Speaking of finishing instructions….here’s what our finishing looks like.

This is my completed quilt top using the Tilda fabrics.

I’ll be sharing my completed Cali & Co. quilt top the third Saturday of January.
Thank you all so much for sewing along! I hope you enjoy making your final block and completing your quilt top. =)
I wish you a wonderful rest of 2025! (I’ll be popping in for one final blog post to announce the winner of last week’s giveaway).

I need to chatch up but I love the finish!
Hi Corey, I love the finishing for this BOM Quilt! I still have all my scrappy stash fabrics out and will be very happy to put more to use. This was such a fun and special program, and I so appreciate all your hard work on our behalf. Thank you (and Ryan), too, for your weekly videos. I learn so much, love seeing your new products and designs, and your personal touches with your treasured finds, gardening and recipes. It’s just like a visit to my home by my most favorite sweet and fun friend. Merry Christmas to you and your family, and please pass along to Nicole blessings for her sweet new baby boy.
I absolutely love the way the mystery quilt turned out!! I have to play a little catch up because of Christmas projects, but I can’t wait to finish it! Thank you so much for your time and inspiration!
How do I sign up for next year and where are the instructions for the bonus project with all those HSTs?
Bonus project being released 3rd Saturday in January.
Hi!Corey, love the finishing. I’ve enjoyed this sew along so much, looking forward for next year. Hope you have a great holiday season, and thank you for all your time and videos.
I loved doing the mystery blocks. Thank you sew much
What about the cut offs for the bonus project?
I also wonder about the bonus project?
Corey said in the video that she will be releasing the bonus project on the 3rd Saturday in January
Thanks for letting us know. I’m not much of a video watcher!
I almost stayed caught up this year. If I take a break from the cookies, I could get caught up or done today. A holiday gift for ME! Thank you for this fun project!!!
Thank you so much for the beautiful blocks . The finished quilt is awesome. I love the way the stars are made. I have really enjoyed this BOM.
I just finished watching block #12 and breakfast can wait. I’m going to go make #12 right now. It’s foggy and yucky here in N. California today and finishing this bright colorful quilt is the perfect way to spend the day. Thank you, Corey, for a great year. Merry Christmas!
Thank you Corey and family for all you do. May your Christmas be blessed….and you get some much needed rest. I look forward to the video each month and think you all do a wonderful job. Love your beautiful fabric lines.
Thank you for a wonderful Year of sewing along i have absolutely loved it.
Thanks for what you do for the sewing community Wishing you and yiur family a merry Christmas and a happy new year and look forward to sewing along with you in 2026
I look forward to your videos every Saturday morning and now on Wednesday, too. Your creativity is inspiring. I’m a little, ok a lot, behind! 🥹 I have one extra block of my own oops design! 😆 Merry Christmas sweet lady! 🎄
This is the first time participating in a BOM online and I have really enjoyed it. I got behind a couple times but am all caught up and looking forward to finishing the quilt top and then quilting it to gift to a friend for a new baby. I used all fabrics from my stash and it is turning out great! Thanks again for providing such excellent instructions and videos.
Thank you tons! I need to get last two done. Have a merry Christmas.
So so pretty! Wow, I love it! I can’t wait to finish it.
Thank you for this project this year.
Who’s the winner for the giveaway?! 😂😂😂 (love the setting, btw & I really hope you do another BOM next year!!)
I have really enjoyed your project this year. Thank you for all your hard work.
One question….what do we do with all the cut off saved corners?
I’m ready to finish this quilt along with you. My colors in the quilt are beautiful. Thank you
Cory for your inspiration. I can’t wait to put this quilt together.
Thank you
Corey, Thanks for the great mystery QAL. I love the fabrics and the patterns. It has been so much fun. Hope you and your family have a great holiday season. I look forward to 2026!
Love it! My 12yo daughter has helped pick the fabrics for each block and it has been a fun shared experience. Excited to see what the “bonus” project will be!
This is so lovely! Thank you, Corey, for designing, sharing, and demonstrating all the elements of this beautiful quilt.
Dear Corey, thank you so much for having this block of the month. I had never done one of these until this year and I learned so much from you. Thank you! Connie
Merry Christmas, Corey! What a beautiful project to end the year! Not there yet but something to look forward to doing in the new year! One request: I have been saving the Cali & Co. fabric patterns and the Tilda fabric patterns so in January, could you send out the Tilda #12 pattern sample? They have all been SO pretty! Thank you so much! Happy, Happy Holidays to you and your family! Take a break and enjoy the season because as we all know it will be gone before we know it! Devonna Tabor
Will there be instructions for the extra corner blocks we cut off when making the blocks?
Hope to finish the quilt this week.
Thank you so much for a fun sewalong. Cant wait to finish mine.
Merry Christmas, Corey, family, and friends. Keep safe and warm. Thank you for the wonderful quiltalong. Looking forward to the new year with Coriander Quilt gang. The shop hop was fabulous and so enjoyable. I would love to be able to come tour the state. Hugs and warm wishes for the ending year and into the next.
Thank you for a great year of sewing!
Hi Corey, I have enjoyed doing the mystery blocks and like the final project. I like to use leftovers on the backs of my quilts but I don’t know what I need to save for the bonus project. Can you at least give us some idea of what we will need for the bonus project? I hate to wait till next month to finish the quilt. Thanks.
This was so Fun!! Thanks Corey!!
Loved this mystery quilt. I hope you are doing another on in 2026.
I have had so much fun doing this project! It is my first BOM sew-a-long and I love it and your fabrics. Thank you so much!
Loved your BOM! Thanks for sharing with all of us!!
Merry Christmas to you!
My quilt will be done and ready to start a new one in 2026. I have thoroughly enjoyed doing this with you. I love mystery quilts and try to always have one going. thank you and I look so forward to your Saturday morning show. Merry Christmas and Happy New Year.

Thank you for the wonderful Quilt Along. Merry Christmas!
I really enjoyed this BOM. It is the most colorful quilt I ever made. I was skeptical at first but quickly fell in love. It is the first BOM I have done with Corey and plan on 2026. Thanks for all you do. Merry Christmas.
I have really enjoyed this mystery block sew along. I am a couple of months behind but will be finishing up the blocks and quilt next year!!
I so hope you will have another coming up!
Corey, thank you for all you have taught us this past year. The BOM process was a blast and was perfect for me, considering I’m living in an RV while we are building our new home. I was able to keep up with each block in my tiny space and I still felt connected with my quilting friends. Merry Christmas to you and your sweet family.
Corey thank you so much for the BOM! The third Saturday of the month couldn’t come fast enough! I can hardly wait to finish it. I’m going to save assembling it until February when my “B” goes on retreat. Loved traveling with you on your Amish “shop hop”!
Corey, thank you for so generously sharing your talents with us. Loved participating in this BOM! Your videos are so delightful. Merry Christmas to you and your family!
Cori I wanted to let you know how much I’ve enjoyed these blocks…thank you for sharing your creative ideas with us….look forward to more in the new year…Barb in St. Louis
Thanks so much for a wonderful sew a long! Merry Christmas and happy new year!
Thanks Corey for another great BOM! Where do I find the Pattern for the Finishing?
I Pray that You, Ryan, the Girls, Tiggs and the KittyKat that we never see, Have Blessed and Merry Christmas.

It’s in the blog post above! =)
Hi Corey!
Thanks for the beautiful and fun sew-a-long. I really appreciate your hard work and planning this for all of us. I still have 2 blocks to do but hope to finish in the new year with Buttercup and Slate.
Wishing you a very Happy New Year!
Just completed my quilt and love it. I sure wish we were starting another one. Really look forward to your videos.
Hi Corey, Happy New Year and thank you for this wonderful BOM. I’ve enjoyed sewing along with my Tilda fabrics. Have to get block 12 done and then the finishing. Hope to share the big finish soon. Can’t wait to see what you’ll have us make with our bonus blocks. I’ve been saving them all in anticipation of another fun project. I look forward to every Saturday for your videos. It’s like a visit with a friend. Filled of positivity and joy. I enjoyed your shop hop through Ohio. Many thanks to you and your family for taking us along for the fun adventure. May 2026 bring you blessings and love, Silvia
Hi Corey!
I love everything Corey Yoder (fabric, patterns, YouTube, videos)! Question for you: I am using the Bloomtopia pieced backing fabric for a couple of grandkids quilts that were born in 2025. Do you have a pattern for other numbers besides the 2020? Thanks and Happy New Year!

Hi Corey,
I just loved this mystery so much that I would like to do it as a Mystery for my Quilt Guild. I am the new President and thought it would be so much fun. Are you going to have this up for 2026? So they could go in and download every month? If not, could I give them a copy of mine. If you need to charge for those, I would so understand. Please email me at ms.marta@gmail.com. I would love them to use your fabric and have a great time as I did.
Thanks so much for such a fun Mystery! Marta
I love the pattern and how it turned out. My question is what to do with the 3.5×3.5 half square from the corners. Thank you
Hi Corey, I have finished the inside of the BOM quilt and am ready for the borders…it was so fun each month to see the different blocks…did I miss the completion for the little blocks that were cut from the corners? I was wondering what to do with them…thanks Barb. in St. Louis….
