Hmm. How thickly does it felt? I've felted with roving and it seemed to felt thickly, and sort of hard. I guess I would try a small sample piece, like a placemat, before doing anything very large. I would quilt it on the dense side, maybe 1" apart(?) as all other battings have been needled or have a scrim to keep them even and the batting from coming apart and bunching up. Curious to see if anyone has tried this before. There are several hits on google about this but they are all from custom wool processers who take your fleece & prepare the batts.
