I had to try this so as I was killing time before a doctor's appointment yesterday (at a fabric store, OF COURSE) I picked up a Hoffman "Bali Pops" batik pack. I had a coupon so it was $22 - not too bad considering it's batiks. (It's a nice pack, only a couple of repeats, and the edges are knife-cut, not pinked) I picked the "cappuccino" color theme with my father-in-law in mind. It went together SO FAST! I didn't pay attention but I think it was only maybe 2-3 hours. I just did straight seams instead of angling the joints - next one I'll do angled and see if I like that better. I didn't press anything either.
It turned out pretty good but it's a little boring. I'm thinking of either doing the "postage stamp" idea that Peckish posted about, or I was thinking of cutting them into blocks and rotating the blocks around a bit, maybe with some sashing. I haven't done a quilt with sashing before so might be a good time to experiment!
