Lately, my art friends and I have been working with Polymer clay. It's such a versatile medium and once it's baked, it's a great surface to paint on.
The following is a small tile that is now ready to be glued onto one of my projects.
The stamp is made by "Crafty Individuals/ Magenta".
First roll the polymer flat and cut out a square the size of the stamp image.
Bake according to directions, paint your background color (regular craft paint) and stamp the image using "Stazon" ink.
Lastly, paint your image using a small liner brush (best for detail work), and if desired, spray coat a matte sealer.
