I've never had a problem with the spray baste, but I do spray lightly on both surfaces as I put the layers together. A light spray and press it together and it holds and I have never gotten a gummed up needle. I suspect it may have been sprayed to heavily and maybe only on one of the surfaces. I lay the backing out, the batting on top, then fold back to half way and lightly spray both surfaces, then pat into place after a minute or so, then fold the other direction and repeat. Add the top and fold back half way, spray lightly, let stand a minute or so, then pat into place, repeat with the other half, then really smooth the whole quilt from center out, pressing fairly firmly, then turn it over and do the same, just to make sure I have no wrinkles.
