Plastic bottle or milk caps, Punches, Papers, Sippy cup
Punch (or cut) the papers into random shapes and sizes. Make sure they will fit on top of the bottle caps.
Apply a coat of Mod Podge to the top of the bottle cap and to the back of a paper punch. Position the paper onto the bottle cap, smooth with your fingers and top-coat with more Mod Podge.
Keep making bottle caps that match. Allow to dry and start making matches.
PROJECT TIP: Store the bottle cap game in an old sippy cup or cleaned out peanut butter jar.
