Step 1 Craft Foam Stamps 1. Each of your craft foam stamps will need a jar lid or bottle cap base. The caps and lids can be of any size or material. Wash them well and allow them to dry.
Step 2 Craft Foam Stamps 2. Obtain craft foam scraps from your previous art projects. The craft foam should at least be around 3mm thick.
Step 3 Craft Foam Stamps 3. Draw your stamp design on craft foam, taking note to match its size with the bottle cap or jar lid. The design can be a simple shape, a smiley face, numbers or letters.

Step 4 Craft Foam Stamps 4. Cut out the craft foam shape.
Step 5 Craft Foam Stamps Ask for an adult's help.5. Notice that my letter "R" is now facing the other way. If you made non-symmetric shapes (right and left sides are not identical), then you will have to flip your shape like I did. Glue the shape onto the bottle cap using a hot glue gun or tacky glue.
Step 6 Craft Foam Stamps Ask for an adult's help.6. Flip the bottle cap over right away and press from the inside of the bottle cap while the glue gun adhesive hasn't quite set yet. This should flatten the adhesive and also ensure a stronger bond.
