Are you ready to add Sashing and Borders with Cornerstones to your Mystery Blocks? Let’s finish off your quilt top!
For the sashing and borders, we will be doing cornerstones which are a new technique for us that we haven’t covered before. Cornerstones are the squares you can see below in between the blocks and sashing. Cornerstones add another level of interest to our quilt top and I can’t wait to show you how it’s done.
I think you are going to be pleasantly surprised at just how easy Cornerstones are.

The finished quilt will measure approximately 47″ x 60.5″
You may find the image of the quilt below helpful to see how we make sashing rows, block rows and then sew them together.

Just wondering about your thoughts on using some of the same fabrics of the blocks in the sashing, cornerstone or border? Or should I go for 3 other fabrics to finish it off, plus the backing.
Great question Colleen. I think it’s a personal preference. But I will be using a different fabric for the sashing. That way no two fabrics that are the same will be touching. Then I will use my white scraps for the cornerstones, and a fabric I have used in the blocks for my border and binding. Any fabric would work for the back. Well at least that’s the plan for now ☺️
Thank you so much, Stacey-Lee . I love to do mystery blocks
Hi Betty, thanks so much for the comment, I am so glad you have loved the Mystery Blocks ☺️
Stacey, thank you for starting the block of the month with us. I have enjoyed doing my mystery block every month. After we have finished, will you be coming up with a new project similar to the MBM. I have learned so much and I did not overwhelmed.
Hi Marcella, thanks so much for joining in on the Mystery Block of the Month. Yes I will be doing something similar again next year, and maybe even a couple of shorter ones. ☺️
Hi Stacie, Was a bit slow lol,…Just finishing my 12th block, I di d 2 of each block to make a larger quilt. Now will try the sashings and borders… can I still follow your tutorial? One silly question but what do you do with a 47 x 60 in quilt because when I think of a quilt I mostly think of a “ blanket” . Thanks and the best for 2023
