I laid out what I have so far and decided that I need at least two more rows long and wide. With those added I'll be at 72" square. It will probably need two additional rows after that to get the length I need for a twin. It would then be 72" x 88"...a decent size. I don't really want to add borders to it. Trying to give it an vintage look.
All of the blocks will have a Snow White border around them. I add oversized scraps of the white...
Then using one of my favorite rulers...log cabin trim tool:
I center the ruler over my block and trim around it...getting a perfect 8-1/2" block.
There's a great 6" marking line on this ruler making it perfect for these...also a nice tool for log cabin blocks. I did a demo for this ruler a couple of years ago. Had to own one after I saw how easy it was to use. It comes in 8" and 12" size. I'm planning on buying the 12" next.
Doing lots of chain stitching today too. This is the quickest way to get the setting blocks made....and I have LOADS to make yet.
