I learned in a class once that the pins you use matter. Don't use the yellow ball pins for detail work, they take too much of a "bite" out of the fabric. Look for the glass head, thin long pins for accuracy. I use the ones by Dritz that have a blue/green head and a yellow head in the same package. They are glass and see thru. I then pin like Prism does without the glue. But I like that idea and may give it a try.
