I didn't mark my fabric either. I did at the start and then when I didn't like it and went with 2 quilts did I remark....NO...So I got out all the instructions and had to go back through and mark everything, then cut, low and behold short, so for this set 1 substitution.- - - - happens I guess?!? Finally all sewed and pressed for each quilt, cut sides even, need to cut the pieces and then will be done. Probably in the morning, then I'll post. Lesson learned....if all else fails "listen and follow directions" imagine that.
