I use Hobb's Thermore and fresh needles and don't have a bearding problem. If I wanted a black bat, however, I would definitely buy it that way. Black fabrics tend to bleed, so I would not want to risk it with home dying.

LadyJaneDoe has it right... go to Connecting Threads, it's 30% off right now. And they're great to do business with, no worries there.

Like others have suggested...buy the black batting...you would really be taking a chance dying it yourself...what if the black then bled onto your fabrics???
