When I first started quilting I had been making clothes for 40 years so my color and fabric choices were very conservative. I combined things the way you would combine for cloths. Going to quilt guild and seeing show and tell expanded my knowledge of what I could do. I've been quilting for over 10 years now and I still see color combinations I wouldn't have thought of. I have made some quilts that didn't turn out as I expected and thought they were ugly, garish or both but there has always been someone who liked them.
I always try to say something nice about others work.
