Sealing wax is fun to play with. This weekend my daughter and I had a blast learning to use my signet ring to seal envelopes.
We ordered this 230 bead set sealing wax kit last week, to fancy up some letters I had to send the kid at summer camp. The kit also came with a spoon and some tea candles. Unsurprisingly, there is not much more to sealing an envelope than that. Heat up the wax over a little tea candle, pour it on to the surface you want it affixed to, then seal away!
I found that waiting until the wax is just melted, when you can still see a bit of unmelted shape at the top of the puddle, was the right time to pour. I would then give the wax a 5 count or so before squishing in my ring. A count to ten and the ring would remove cleanly, without ruining the seal.
Two beads is the right amount of wax for my ring.
Mixing colors is really cool.
