Comment: From the PM that I sent after the swap (and got no reply):
I got your package, and I'm sorry to say that I don't think it meets the swap requirements. I like most of the fabrics you sent, but the box wasn't as full as it should be for a flat-rate swap. The whole point of using a flat-rate box is that it should contain enough fabric that it is heavy enough that it would be more expensive to ship it normally. The box you sent was only about 2/3 full (or maybe even only 1/2 full, if you packed it down), and obviously was light enough that you reboxed it to save money on shipping.
Sorry to be a stickler, but I believe swap-bot only works if people rate fairly.
