it is fused with ultra bond lite. I had used that on the hyacinth one I did recently & although I really don;t like the stiffy feel, the misty fuse was not working for me either. I think because I do soo much manhandling while twisting & turning that I was loosening the misty fuse. I was having a similar problem with the heat & bond lite, but not as bad so I stuck a few pins in just in case as I have 3 other tops to finish off before I can sew these guys down.
P.S...I do have parrots
