I have nearly 2 yards of this material (found on an "unwanted fabric" table at a guild meeting). There is just enough width to be able to get what I need. The color is actually a deep Indian red (rather than the rust color it shows).
I have discovered that stitching goes a lot faster if the triangles are all stitched down, then add the tops later. The green you see under the triangle color is what I use for the tops. It is far more challenging to get the proper amount of fabric for the template and still have the graduation in color I am looking for.
