I have had the skipping stitches problem. I do use a lot of vintage sheet fabric, so that may have contributed to the problem. I did a couple things that helped.
I have a Bernina so I have to oil my machine. When I am quilting something that's been spray basted I take the oil, which is clear, and put a drop on a tiny bit of fabric or paper towel or whatever and rub it on the needle. I repeat that once or twice during a lap size quilt. It keeps the little gob of glue from showing up on the needle, so I am sure it is helping.
Also, and I think this is more related to the sheets than the spray, I use a jeans needle for quilting (I think it's 90/12?). It says "Jeans" right on the package.
I still sometimes miss a stitch, but not nearly as often. I do find it interesting that it might be using too much spray- that is very probable. I am a more is better kinda gal and that isn't always a good thing. I will start using less and maybe the whole issue will go away! That would be awesome.
