Steps

Step 1 Craft Foam Stamps 1. Collect jar lids and bottle caps. Wash them well.
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. Choose a bottle cap or jar lid that is just the right size for your stamp. You may trace around the bottle cap to guide you while you draw your planned stamp design. It 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 help5. 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 help6. 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.
Step 7 Craft Foam Stamps 7. When the glue dries, your stamp is ready to use.
Step 8a Craft Foam Stamps 8. Here are some more notes and ideas for making your stamps:

a.) For symmetric shapes, you may glue on any side since the right and left sides are identical.
Step 8b Craft Foam Stamps b.) Try combining smaller shapes to make a more detailed stamp. Take extra caution when gluing on small shapes with a glue gun.
Step 8c Craft Foam Stamps c.) You can make outlines instead of solid shapes.
Step 9 Craft Foam Stamps 9. Use the stamp by dipping onto paint or pressing it onto a stamp ink pad. Shake off any excess paint and stamp onto paper.
Step 10 Craft Foam Stamps 10. Wipe the craft foam stamp when switching to another color of paint or after you have finished using it.

If you used hot glue gun instead of tacky glue, then your stamps should be washable.
Step 11 Craft Foam Stamps 11. Crafting your own stamps is an economical and an earth-friendly alternative to purchasing brand new stamps.
