Some progress pictures.
I gave up on the strip piecing idea pretty quickly and have just been soldiering through the set in seams. I said it was going to be a riot of colour - I think a shotgun blast of colour, direct to the midsection, would have been more accurate.
I've been using nothing but scraps left over from other projects, after experiencing some weird cosmic guilt in Hobby Lobby. People were waxing $16 on crappy plasticy looking pre cut tiles for a mosaic and it suddenly seemed so retarded. Surely half the fun of making a mosaic is smashing up your old tiles, or old plates or whatever, crafting something cool out of stuff that would normally be consigned to the bin. I figure half the point of making a quilt is to use up your crappy little leftovers, not buying up convenient colour coordinated fat quarters at $1.49 a pop, so it's turning out pretty random.
Here's a few blocks pieced together already and a few other large single blocks.
