I have seen it in LQS, the projects were awesome too. There are several pdfs available if you google it, on using it in the top and bottom, top or bottom only and in embroidery too :D:D:D
Interesting on the prices... I have seen it for almost $10 for a 300 meter spool up to $20 for a 3000 meter, big difference LOL
