Scrappy quilts are traditional. The key is to work in values and not in colors, Say a pattern calls for 10 dark, 10 medium, and 10 light. you choose your material by that.
the storm at sea is a great quilt to do this way, and you don't notice the colors individually. The only thing is you have to like the material to begin with.
I on the other hand, can't make my self make a quilt with only 2 or 3 colors, just can't get into them! LOL
I love your quilt , it is striking!
