Hi Pam
I don't know what you used but I've used some brands that were stickier than others. I've had good luck with Heat-n-Bond LITE (NOT the regular...that's a nightmare! LOL) and I use a top-stitch needle when working on bonded applique. I love the top-stitch needle (standard point 18/110) for this and for working on heavier fabrics such as flannel.
I've never noticed my needle gumming up when I use the LITE and I go a little slower in these sections and haven't had much trouble with skipped stitches or tension issuses. Good luck! :)
Not long ago, I accidentally used my regular Heat-n-Bond on a baby quilt, and wound up having to do the applique quilting by hand...using a larger, stronger needle and a big stitch. It was just awful!! I'll never make that mistake again. :oops:
