M.I.Late

I have had the same exact problem with warm and natural (guaranteed not to beard). My backing was also dark. In my case black on black. Mine was machine quilted by a long arm quilter. Two at the same time. My twin black, white and brights quilts. She said she changed needles a dozen times, called Warm and Natural mfg. showed them to other quilters while they were on the machine. No one was able to figure out what was going wrong so she just continued. She called me and said there was a little bearding going on, but that I should be able to use a lint remover to get them off. I said well, ok. She sent them back to me totally bearded. I mean it was bad. I ended up ripping both quilts all the way out. It was just too unsightly. My solution? I changed to a black poly batting. The problem with it though was that I had some whites in the front. I didn't want those to appear gray, so I lined the entire quilt. My sandwich had 4 sections. I hand basted the white lining to the black batting so it would still go on the long arm in three pieces. It was beautiful after that and no visible bearding at all. It may have been there - but you couldn't see it. Wish I had better news. But you did say the back was hunter green. That's pretty dark too...

I hope changing the needle from the "self threading" works...

BTW I'm Gayle M too.
