They can be painted, stained, decorated and varnished. How you finish them is entirely up to you.
Step 1: Materials
For carved pendants, earrings etc., you will need a pencil and some small sharp tools to carve the material.
For cuff bracelets, you will need a pot of water, a stove, tongs (to remove sticks from boiling water), fabric pot holder and a small canning jar. Why the jar? Well its a nearly the perfect size for shaping the cuff bracelets. Canning jars are preferred if you want to speed up the drying process, otherwise, you can use any jam sized glass jar.
For all projects you will need sand paper in varying grits (medium & fine grit), wood varnish to protect finished pieces and a brush to apply varnish.
If you want to embellish your wood jewelry pieces you can easily use small stickers, sticker letters, nail art decals, or adhesive gems (normally used to decorate cell phones). All these can be inexpensively purchased from craft stores, or dollar type discount stores.
A drill and a small drill bit will be very helpful in getting the holes made for pendants or earrings, but I was able to make holes using the sharp tool I carved with, so this is optional.
If you prefer, you can easily paint or stain these pieces. Just ensure that the paints and stains you use are compatible with your varnish. Use all water-based or all oil-based products. DO NOT mix water-based and oil-based finishes.
Note: If you use adhesive gemstones, you will need to either apply additional layers of varnish, or consider purchasing a thicker varnish product, available through most home improvement or craft type stores.
