The 2026 Designer Mystery Block of the Month is about to start, and we’re sew excited to share a sneak peek with all of you! While you will have to wait to see all 12 blocks together, today we’re sharing all the details you need to know to get started. This year’s Designer Mystery Quilt is stitch-themed and imbued with the timeless colors of the A Cat Named Stitch collection by Camille Roskelley for Moda Fabrics. Join us in making the 19th Annual Designer Mystery Quilt by Fat Quarter Shop!

This year’s quilt finishes at 68.5″ x 84.5″. The Designer Mystery Block of the Month runs from June 2026 through May 2027. Members will receive a block pattern and fabric each month (and don’t worry, there’s a little extra included to allow for starching or miscuts).
The Block of the Month consists of 12 blocks designed by 12 Moda designers, and each block finishes at 12″ square. Keep reading to meet the 12 wonderful designers at the end of this blog!


Block of the Month Supplies
The 2026 Designer Mystery Quilt is exclusive to Fat Quarter Shop, so you won’t find it anywhere else! To make your quilt just like ours, pick up the Designer Mystery Finishing Kit, which comes in a beautiful coordinating keepsake box — perfect for holding your blocks and patterns! The Finishing Kit also includes the pattern and fabric for the sashing, borders, and binding to finish the quilt in stitchy splendor.
When you reserve the Designer Mystery Backing Set, you will receive 5.25 yards of this gorgeous floral print, along with a bonus quilt label, available exclusively with the purchase of this backing set. Both the Finishing Kit and Backing Set will ship with your first shipment of the Block of the Month, so you will have all your finishing supplies on hand.




Optional Notions
If you would like extra help making perfect half-square triangles without the fuss, we suggest using Triangles on a Roll Triangle Paper in H200, H250, H300, and H400. For some help making flying geese, we recommend the 1″ x 2″, 2″ x 4″, and 3″ x 6″ Foundation Papers. The 2″ Square in a Square Paper will also be helpful for some blocks. These notions are all entirely optional, but you know how much we love using Foundation Papers!

Guest Designers Featured Each Month
Twelve incredible Moda Designers contributed sampler blocks for this year’s Designer Mystery Quilt! You may recognize some familiar faces and even meet some new ones. We can’t wait for you to get to experience the wonderful design skills of each of these 12 designers in one quilt!

As you can tell, we are sew excited to get started with 2026’s Designer Mystery Block of the Month! It runs from June 2026 to May 2027 and will ship around the 10th of each month. Don’t wait to grab all the goodies for this year’s Designer Mystery Quilt because spots are limited, and when they’re gone, they’re gone!

I’ve made several Designer Mystery Quilts now. I’ve found that the FQS mystery quilts are one of the only mystery quilts which I actually love the finished product every time. The difficulty level is just right and they are always heirloom quality.
This looks intriguing! Is the only way to participate is by purchasing a fabric kit? Thanks!😊
This will be my first time participating and really looking forward to starting. Love the fabric line.
I’m not sure, but I’m guessing you can use your stash, once you know the fabric requirements; I am considering doing this using my stash and just getting the monthly patterns to reduce my cost. My stash is huge so I can do this.
The only way to get the patterns while the BOM is running is by signing up for the monthly kit which comes with the fabric (around $22/month plus the one time reservation fee of $4.99).
You can just sign up for the monthly kit and not the finishing kit ($130) or backing kit ($75). If you sign up for both/either the finishing and/or backing you’ll get them when the first block ships.
You will be able to purchase the full pattern set (without any fabric) once the BOM is over. I’m not quite sure if it’s immediately after or you’ll have to wait a few weeks. It’ll be around $60 for the set of patterns.
My experience with these Block of the month kits are great! Beautiful. Fat Quarter Shop is very generous with their fabric, allowing for startching, errors and een making extras, I’ve even made 2 of the same quilt! Thank you Kimberly, Kevin and team.
Thanks! I’m not a cat fan, so while the color palette is lovely, it’s a bit of a deal breaker for me. I have a large stash too, and I think it would be really fun to mix a variety of fabrics while kinda sticking to a color theme. 😃
Thanks Liz. That’s disappointing. This year will be a pass for me, even if the patterns are available later. I want to be part of the BOM community DURING the BOM. It’s much more compelling for me to stay focused on the project that way.
Is there an option to just purchase the patterns monthly and not the fabric? I would like to use what I have in my stash!
Not while the BOM is running. They’ll make the set of patterns available sometime after the BOM has ended.
I am not sure how many years I have been getting the Mystery Blocks of the month and each year they get better and better. I love the colors that are being used in the 2026 BOM and can’t wait to see the first block. I have gotten BOMs from other sites but none of them compare to what you do at FQS. I often have enough fabric left to make a second, smaller quilt. You have my eternal thanks for such a great club.
This will be number 5 for me and the FQS does BIM better than anybody – generous amount of fabric, clear instructions, high quality it’s worth the time and money. I also love the support we get from the FB group making subtle changes in the patterns or the choice of fabrics and final quilt !
This will be my 4th time joining this block of the month club! My first time was 2014 then I joined again in 2018, 2022 and now 2026! I’ve done other BOM clubs but this one is my absolutely favorite!
This is my first Mystery Block subscription and I’m excited and a bit nervous, but definitely looking forward to it.
This is my first mystery block of the month with the Fat Quarter Shop. I’m looking forward to it!
