I am/was a matchy matchy quilter. I would pick out a print, then take colors out of the print. Solids, blenders whatever.
Since I have lots of scraps because of the amount of quilts I have made, I had to just start making scrappy quilts.
It wasn't real hard, just started sewing strips together. Used sashing all the same fabric and I liked them. I give most of my quilts away and no matter the colors or patterns they are still well sewn and warm.
Remember different strokes for different folks.
