I Tried to make dog beds with the scraps from trimming, but when I washed the bed for the first time, everything kinda clumped together and was hard. How do you keep them fluffy? I did put them in the dryer, but they never fluffed back up. I had quilted about 6" apart to make baffles so all the scraps wouldn't clump in one spot, but they clumped within each 6" square.
