This was my project for the past 3 days while being snowed in. It was fun!
I cut them at 5" and followed Jenny's instructions. This was really really fun. I have one tip for you, be sure to press and not iron. Handle the pieces as little as possible and try not to stretch them. :) I always learn the hard way. LOL I didn't have to trim my blocks. They all came out to be the same size. The border is 3 1/2" unfinished. The dotted material and stripes material are from Robert Kaufman.
If you have any questions, please email me.
Have a great day! Enjoy!
