Here are my pics.
These are 4 inch equilateral triangles, with a 1/4 inch seam allowance. Most are sewn in rows, others are sewn like log cabins. They are a lot of fun and very addictive. I'm using leftover homework for the papers. I got that idea from Crazy mom too! I have 10 purple triangles.
Here they are in a row. I haven't decided how to sew them together yet. I am going back and making 10 of the colors previously used in the rainbow scrap challenge (red, blue, green). I think I will alternate colors and have the same colors make a diagonal row!? I have until January to figure that out!
