I've decided on my layout for the green & cream half-square triangles I started the other day. I did a test block - it has 36 squares and finishes up at about 12 inches.
I have calculated that I'll need 900 squares to complete a queen size quilt. More if I decide to not include borders. So, my measly pile of squares will need to be much bigger.
I'm really happy with the color combo. Just enough variation to look scrappy but not so many to be too bright and vivid (not that that's a bad thing, just not what I'm going for on this one).
