Great job on your blocks!!! :thumbup: I love them in the Christmas fabrics!!!
~ another now added to my list! lol!!!!! :D
It's funny how you think you're sewing each seam perfectly, until you measure them.... The quilt top I just finished for my daughter started out being 7" blocks. They all ended up a perfect 6 3/4"! Some were a tad too short, so I shortened them all on each side. I could cheat as I was the one who made up the pattern. lol!!!
I think I'm going to copy your idea and mark my machine too, at 3/16th, as I usually have the same issue!
