Mystery Quilt: The Stoplight Quilt

I am taking a quilt class with a group of women from our congregation. The teacher chose a Mystery Quilt called The Stoplight Quilt for us to do. This was a little challenging for me to pick the fabrics not knowing at all what it looked like. So I went a little on the plain side but I thought these 4 colors would look great for a nice Autumn quilt.

This is Part 1, 2 and 3. These are the 2 pieces (64 of each) I had to have completed by the 8th of August, mine are complete. But I am a little nervous. I have never done triangles before or things with a rounded side. But I guess we will see how did I on Saturday and get Part 4.
