Dina, you are on the right course. I have told many quilters to lay out strips of fabric on a design wall and look at it many times a day. I even ripped out a fabric that once cut, was NOT working well. I do like your colors but I am slightly worried about that screaming yellow. If it doesn't bother you. then go for it. When you put so much effort into a Bargello, you don't want to make a mistake. I am starting to pull fabric to work on one Eileen Wright's quilt from her new book More Twist and Turn Bargello quilts. Good Luck and look forward to photos of the progress of this quilt.
