Those sewing machine needles I use on the wall are not just dull needles, they are broken. The sharp tip is gone, and there is usually plenty of shank left to pound it into the wall. If you have dull needles it should be easy to take a pliers and break off the tip and a half inch or so. I've never had one come out by itself, and they don't come out easily when I want to remove them. A little wiggling or a pliers does the job.
