I am better at color choices than I used to be. One of my ahHA moments with color was 'auditioning' fabric on my design wall. If I wanted a yellow, I would put up about 5-6 diff yellows on the wall with the other color choices. As I would walk by, one would say NO WAY..down it went. Sometimes I have 2 choices. I will take one down and see how it feels..then the other. My husband gets roped in now and then...not sure how thrilled he is about THAT! He is trooper tho and will give his opinion. Occasionally now, I will finish a quilt that is not QUITE what I had in my minds eye. I try to figure out why..and tuck that away for later. I often pick a border fabric FIRST, and the other fabric to match that. Just remember: its not rocket science...and you can learn something from each quilt you make.
