I think I know exactly what you are asking - here is a photo of one of my quilts in progress and there are small holes where the pins were. I don't pre-wash my fabric (my quilting teacher advised not to) and I don't wash them before I give them away, so I'm not sure how to get rid of these. I've tried lightly scratching at them with my finger nail but it doesn't seem to help a whole lot. Any ideas?
