If it is just the raised head type, take some RC-56 canopy glue open it up and let it get a little thick then you can take a tooth pick and dip it in and touch the surface and make them, I like to use a needle fill the tube with wood glue and let it drip out the end and touch the surface, I cut the sharp point off. With a little time you can make tons of them. And with defferent size needles you can have any size you need
