Hi, Pewa88 -- so glad you're joining us. We'd love to see pictures of the blocks you've done so far. Are your blocks 5" before joining them to the sashing or 5-1/2"? The original Dear Jane is 5" before adding the sashing (or 4 1/2" after the sashing is added). Since I'm lousy at math, I've stuck with the original DJ measurements so I didn't have to figure anything, especially when it came time to add the triangles. So the blocks are 5" unfinished and the sashing is cut 1" wide (or 1/2" when it's joined to the blocks). I cut the 1" strip into 5" pieces and joined the blocks to each other row by row, then I added a long 1" strip at the bottom of each row. Some people have put cornerstones on the long sashing between each block, which may end up being easier because you're only sewing together 5" plus 1" for the cornerstone at a time, but the long sashing worked fine for me.
