These are the brown glue sticks I got:

These are a bit of a pain, since thy are "mini" glue sticks about 1/4" diameter. To feed them in my glue gun, I have to push them in manually, and then use a normal glue stick behind them to serve as a plunger.
You can buy normal 7/16" diameter colored glue sticks, but I could only find them in larger quantities than I wanted. If anybody finds a good source for 7/16" brown glue sticks in small quantities, please let us know.
Likewise, if some finds a better color, like tan or grey, it would be great to hear about it.
