I've been looking at several methods to create my own CPSIA tracking labels. I found most of the helpful info here in these forums and I've tweaked some of the ideas to create a very easy printable label, which I can sew into the seam of my stuffed toys. Just print, cut and sew them in. I've posted full instructions here
http://sockmonkey.shopping.officelive.com/labels.aspx and I've also included a template for the labels to make it easier. These are 100% cotton labels printed with ink jet (CMYK) ink printer, so they are CPSIA compliant, no lead or pthalates are in them, so no need to have them tested.
