You’ll need craft-store wicks, wax (or old candles) that can be melted down, old teacups, and maybe a fragrance or two. Pretty single teacups (with or without saucers) can often be found at thrift stores for less than a dollar. Melt the wax in a double boiler, add fragrance if desired, then support the wick standing in the teacup while carefully filling the cup with wax. As the wax cools, it will contract and form a well. You can add more melted wax of the same color or add a second shade. These are fairly easy to make,but beware cups with obvious cracking; the hot wax may cause them to shatter.
