The one and only time I used fusible batting it bled through to the face fabric and didn't come out when washed. I ended up sending the quilt to the June Tailor company. They reimbursed me for the batting and somehow were able to get most of it out. They must have needed a really strong chemical because the quilt stunk so bad when it came back. I rewashed it 3 times before I could send it on to the hospital.
So needless to say I've gone back to pinning. SVAL
