Knot my problem

Ever get these little knots when appliqueing? I do. A lot.

I remember a quilt teacher (can't remember which one) told us how to easily fix these types of knots by putting the needle at the base of the knot and pulling up until the knot pops out. The pictures explain it better.

It's been a great tip for me over the years, and it occurred to me I should share it.

If anyone has tips for the other kinds of knots I seem to get in my applique, I'd love to hear them.
