2023 Designer Mystery Block of the Month - The Jolly Jabber Quilting Blog

2023 Designer Mystery Block of the Month

Keeping this secret under wraps is no easy task, but our 2023 Designer Mystery Block of the Month will be worth the wait! This quilt stars florals and inspirational geometric designs in 12 sampler blocks made with Sunnyside by Camille Roskelley for Moda Fabrics in a palette that’s sure to brighten your day. Join us in making the 16th Annual Designer Mystery Quilt by Fat Quarter Shop.

This year’s quilt is Full Size, finishing at 72.5” x 93.5″. The Designer Mystery Block of the Month runs from June 2023 through May 2024. Block of the Month 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 is made up of 12 blocks designed by 12 Moda designers, and each block measures 12″ square.

Here’s a teensy sneak peek. Can you guess the rest?

Block of the Month Supplies

The 2023 Designer Mystery Quilt is exclusive to Fat Quarter Shop, and you won’t find it anywhere else! To complete your quilt, pick up the Designer Mystery Finishing Kit, which comes in a beautiful coordinating keepsake box perfect for holding your blocks and patterns. It includes the pattern and fabric for the sashing, borders, and binding to finish the quilt.

Reserve the Designer Mystery Backing Set to receive 5.75 yards of this lovely floral print and a bonus quilt label available ONLY 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.

Fabric Requirements

BONUS: Since our BOM is generous with fabric, you’ll often have enough to make extra blocks! Cutting instructions for 3″ and 6″ blocks will be shared each month in the Designer Mystery Facebook Group and below! You can find out more from Kimberly in this Fat Quarter Shop Livestream video!

Optional Notions

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

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.

Happy Quilting!


    1. I understand this club might not be for everyone, but you get a LOT of fabric for the cost – sometimes enough to make an additional quilt! Also, we have lots of free quilt alongs that we host during the year, and you are welcome to join us for those. 🙂

  1. Hi! This looks like it’ll be very pretty. Can anyone tell me how much total yardage (approx) will be included in this – including the quilt blocks, the finishing kit, and the backing? Thanks so much!

    1. Hi Anna, we don’t provide this information for the designer mystery quilt typically. This is designed to be done as part of the club, and the only way to get all the information is to be a part of it.

      We may end up sharing the fabric requirements if the club sells out or after it ends, but that’s not guaranteed.

      Hope this helps!

  2. I would like to make this quilt smaller. Can you tell me if all the blocks could easily convert to a 9″ block?

    1. Hi Gayle!

      Yes, the Designer Mystery 2023 blocks can be converted to 9” size. However, the smallest finished unit in the 12” blocks is 1” finished, so that would convert to ¾” finished. If you like working with units that small then it is absolutely an option!

  3. Unfortunately living in Australia and postage etc being so very expensive plus unreliable it is impossible to participate in this design mystery. When I was getting the sew sampler boxes they were taking anywhere from three to six months to arrive and some never arrived at all. This being the reason for me not continuing to purchase them.

  4. I would love to make mine king sized. Can you tell me if there is enough material included to make the extra blocks needed? I don’t even know how many blocks that would be? I have already pre-ordered everything. I was hoping I could made duplicate of (x number of blocks)? Any ideas here?

    1. Hi MiChelle!

      Due to the nature of this month to month quilt club we only can say you’ll have enough fabric for the size quilt this pattern is designed for. In 2023 that is a full size quilt. You can always take the patterns and do some math once you receive everything to see if you can make it in a King, but we provide enough fabric only for the intended size.

      Hope this makes sense!

  5. I am cutting out my 2022 Mystery BOM and there is such a GENEROUS amount of fabric in it that I probably could make two blocks for each month. Wow! I am so impressed! Thank you Fat Quarter Shop! I am also signed up for the 2023 Mystery BOM.
