The first one is called Twin Sisters. I would be totally scrappy. I experimented with a couple of sizes. I really like the large blocks when piecing a large quilt and the small one for maybe a tablerunner or corner blocks.
I think this one is called Twirling Triangles. This one I saw on Fons and Porter. I just happen to have a 60 degree triangle and thought I would try it out. I like it. I goes together great,. No "y" seams, just straight line sewing. I've made a couple of halves. This picture was taken when I'd only had one done. I like it.
