Most of my quilts are gifts so first thing I decide is what color(s) would be appropriate for the person. I really like brighter colors but sometimes the person the quilt is intended for likes everything kind of neutral. Got a surprise when the fabrics in the quilt kit I ordered for a dear friend's quilt were a lot bolder (really louder) than I expected. You know what? She loved it, said she sleeps under it every night and that it added a little brightness to her home. So I guess just go with what you like and it will be OK.
Presently I'm working on 2 baby quilts for soon to be born grandnieces. Instead of pink quilts I'm making one quilt in yellow and blues and the other will be scrappy 30"s Repro fabrics with white background. I'm sure the new babies will get plenty of pink stuff. May in Jersey
