Steps of progression

I had planned on a detailed post today about one of my wallhangings but I got up with a weather related headache and can't think so I'll do an easy one. This is one of my bright colorwash pieces in progress. I start with lots of trays of 2 1/2" squares cut from hundreds of fabrics. Then I put the pieces up one at a time. I used to always start at the center with light but lately I have been starting on an edge. I continue adding pieces, and removing some that didn't work well.
I blend color into color in the order they are on the color wheel or it may be decided by what colors were in the previous piece of fabric.
This piece is almost completed. The picture below is the piece all sewn together, but since then I have added 3 more rows to the bottom, and because the ratio of width and height aren't quite right yet I will still be adding a few more rows. I will show it again later when I have all of the extra rows sewn on.
