I am sure someone ill have the proper solution but I had to sew though some stick on Velcro circles. They were very sticky and I took a drop of my sewing machine between my 2 fingers and smoothed it up and down my needle to remove the gunk that was stuck on it and it helped lubricate the needle. This might help you but make sure it is a very slight bit so you don't get oil on your appliqués. Some of sewer's aid might work too?
