This is too big to spread out where you can see it all, stansgran All of it is from some furnishing fabric sample books that I found thrown out by a shop. Like you, I had enough material to ignore them, but I am glad I didn't as they all complement each other perfectly. You could use the larger pieces of your stash as the squares and the smaller bits pieced together for the strips between them.
I looked for another quilt I made from a booklet called "Strip, trip and shadow quilts" but it seems to have vanished off the face of the earth. You sew together long strips of several colours, then sew a wide strip of self colour to them and cut triangles, which you arrange in patterns. It sounds more complicated than it is, and the effect is great, without too much fiddling around. When I find it I shall take a photo and post it - and I'll try to scan the instructions too and post them (if possible)
