I usually put a few drops on a piece of aluminum foil, or a small glass plate. Then I use an X-acto (or equivalent) handle with a piece of small music wire chucked in place. I simply dip the wire in the glue, and apply. If you want to apply a slightly larger dollop of glue, simply bend the wire tip into a small loop, or cut the eye of a sewing needle in half and chuck that in your handle. There are also ready-made applicators on the market, if you want to spend money. Check out www.micromark.com
Hope this helps
