Place one of the images onto the acrylic block.
Heat up your wood burning tool.
Cover the stamp with ink and then very lightly press it onto the wood slice, just enough so that you can see the image.
Then take your wood burning tool and just follow the lines as you like. You can use the tool to do some shading if you like to enhance the motifs even further.
Once you are finished with the wood burning, drill a hole at the top center of the wood slice, pull a piece of twine through the hole at the top and add a bead if you like. Knot the two ends together.
