I'm having the same problem with a quilt that I am making for my niece for Christmas. I had her pick out her own colors and she went with lime greens in a large print, and mostly browns, dark, med and light. There is a small 2X2 square of blue in the center.(quilt is 60X60). I need at least 15 more colors to finish the blocks that go around the center block and not sure what to pick !!! More blues really tie it together but she says she's not really a blue person !!! I'm looking for more of the lime green and will add some more blue but its getting late !!! They are a version of a log cabin block so hopefully I will be able to pull it off. I'll post it if it ever gets done !!!
