It all depends on the fusible you used. I made a Nativity scene a couple of years ago. I really doubt it will ever be washed. I used Steam a seam which the instructions say are washable. I didn't believe them. I fused a couple of pieces down and ran them thru the washing machine 6 ties and they still looked good. I ran it thru the regular cycle pinned to clothing. Loads of jeans etc. I just fused mine and didn't sew the pieces down. There were pieces that weren't much larger than the head of a pin.
