I buy Kona solids in bright colors for my crib/lap quilts. I really like the bright colors with machine embroidery blocks. Using the solids don't take away from the embroidery design like a print would. I think a few solids should be incorporated into quilt blocks. In my opinion all prints can get a little busy. And solids allow your eye to slow down and see the colors. With too may prints your eye roams around and around and really never stops to see the colors/fabris,design.
