I was doing a BOM at my LQS, they cut some of the pieces so small, that the tiniest bit of fraying caused them to be too small to use. Twice they completely omitted a fabric, and told me that it was there when they packaged it. Well, it wasn't when I dumped out the envelope on my table LOL I ended up dropping out.
I will try again someday, just not through them :D:D:D
