somethings wrong. I was practicing today with one I sprayed with sullivans with no problem, probably over spray or like they said, not letting dry maybe. I t shouldn't be causing problems

It may be that you are using too much, as you thought. I use Sullivan's all the time and have never had a problem. Use it for hand quilting also and never noticed any on my needle.

I saw on the 505 can that it is not water soluable. Does that mean that it stays in the fabric forever?

I used to use Sullivans and loved it but they changed the formula and I have had problems since then. I am going to try the Elmers Glue next time.

Not a big fan of sprays. My issue though. I end up with more on me than the quilt. I have used it and after letting it dry overnight, didn't have a problem.

I have used too much before and had the same problem. Just give it extra time to dry.

I have used June Taylor's basting spray as well as Dritz. Both worked well and I didn't have a problem with needle gunking up.
