Anyway, this is "D-11, Snow Crystal", an intermediate-level block that I rotary cut (the background) and then used the raw-edge machine buttonhole-stitch applique method for the dark red pieces.
This is one of only three blocks (that I know of) in the center of Jane Stickle's quilt in which she used more than two fabrics. Here's what hers looks like.
It's a very subtle difference, but if you look closely, the outside four small diamonds are cut from a different fabric than the large triangles and center square. I tried to make the look in my block subtle as well.
The other blocks with more than two fabrics can be found here (four fabrics) and here (three fabrics). I haven't even begun to look at the outer triangles, so I'm not sure if any of those use more than two. We shall see...
