I have been following your DJ discusion and now I think I have to give my humble opinion to it:
Looking at my (already finished and assembled) Blocks and the Triangles (finished but not assembled yet) I cant picture a DJ with anything but a plain color background fabric.............UNLESS you make the blocks with plain color fabric!?
All this delicate corners and lines might mingle if you use for both a printed fabric. Did you ever had a perfect sewn corner and in that exact corner a dominate part of the print and steping back it looked distorted!? AAAARRGGGG..... the limitation of my english skills (we should comunicate more QuiltE)............do you know what I want to say??
So why not thinking of plain color fabric for the blocks or even better: prove me wrong!!
QuiltE: I fully understand your feelings. You want to make the DJ DIFFERENT. I had that idea too before I started. But I think the DJ is like Swiss chocolate: you cant make it any better. lol.
