Most of the responses have suggested washing or wetting your quilt. I sent the note about lighter fluid. If you use it, you don't have to wash or even wet your fabric!
I say, "Leave the chocolate where it landed. It had an important purpose in the making of this quilt!" Put a small applique over it and allow it its place in the quilt. Just my thoughts LOL.
Who Knows?????Just leave it in and have a mighty sweet chocolate Kiss quilt. LOL Hey, sounds like a good theme for a quilt. Chocolate kisses, mixed with kissing lips.
