Post #543 has information on making lip gloss with stamps from Clear Dollar Stamps. I ordered the stamps and my son made lip gloss to sell to the neighbor kids this week. You can see photos on my blog. (Sorry, I am not good at linking yet).
I used bead holders to hold the lip gloss. They are small round clear platic holders, sold in a tray of 24. Walmart had them for $6.49 and Joann's sold them for $9.99. They were the perfect size for this project. A 1 1/4 inch punch works perfect for the top design but my son chose something differentto use.
