UGH. I don't mind doing math. As long as I know wth I'm doing. lol I think I have it figured out but I am hoping someone can confirm for me.
So since I am cheap I am using a regular square ruler with a 45* line to make HST the tube quilting way. I want my blocks to FINISH at 4 inches square. If MY math is right I have to cut two strips 3.75 inches wide, sew them down both sides then cut them apart lining the 45* line up with the stitching and so on.... I know a ruler that is made for this would tell me how wide to cut the strips but I'm cheap.
Thanks to anyone who can help.
