I have some panels 10" square (Catitude) and I want to make a column quilt with braids the same width - 10"

Now there are plenty of How To tutorials out there - not the problem. But there are no charts that give width of strip - length of strip and width of final braid. So 8 don't know how long to cut my strips to get them to match.

I happen to be using 2.5 jelly roll.

Thanks in advance
