Great news, blog readers! Today my shipment of fabric bits showed up, AND they managed to follow my directions and label them!
Now all I need to do is make a final decision about which one to use, and I will be all set to place my order. By my reckoning, any one of these will dye down to be a very good approximation of the color I want, so it's really all about the size. Assuming I have time to get around to measuring them tonight, I may very well order the stuff tomorrow.
