I've ordered two more fabrics that will go in, but here's how it's looking right now:
There are 100 different fabrics in the colorful block. At first I was worried that I may not have enough individual fabrics to do 100 squares without repeating, but... yeah, that wasn't a problem. The little squares finish at 1", and not wanting to piece all that traditionally, I took a look at something that had stuck with me for a long time: this tutorial on using fusible interfacing to quick-piece little squares. I didn't have interfacing and was looking for something that would be less rigid, so I worked with a piece of muslin and a glue stick.
