Toothpicks are a good choice as they are disposable, or as I do re-sharpened occasionally, with my #11 blade. I tend, though to use a tapestry needle ( it is just a large needle that is blunt on the pointed end) as I get a more reliable "rivet", and it is one of the 2 only times I will use Elmers-Glueall, as I can place a squeeze on my left index finger, hold the model in the same hand and pick up a dab with the needle and apply it with just touching the surface of the model, with the glue. It ( as you have probably found out) takes a bit of practice to get consistent results. I will usually make one pass with the needle, then when dry add another on top, which adds just the right amount of rivet shape. Elmers has just the right liquid quality to work well and dries quickly for this purpose. If you mess up, you can just wipe it away while wet and do over.
( The only other time I use Elmers, is to laminate thick card, by spreading it on one surface with one of the hundred or so plastic cards that come in the mail for me to go in debt with, it spreads well, and using a roller makes a great laminate, it must be weighted down, however, or you get the inevitable warpage)!
