Hi Joan Welcome
I have made two of them, will post pics when I get home from work. The number of different fabrics/colors is completely up to you. My first I only used four or five different fabrics, the second I used a collection of approximately 20 different fats. In fact I have the blocks done, but haven't sewn them together. I might just do that this evening for you :)
This is a great quilt if you are beginning. The first time I made the quilt I did make some of the blocks backwards but it came out ok.
