Today, I posted 3 letters to different corners of the world. One of the envelopes is sealed with wax (below).
Last year, I had the idea of making my own seals. I bought some modelling stuff and made this. I had left it to dry and forgot about it. I found it last night and thought I would try it on a letter to the US. I had surfed online for ideas about them and one suggested using an oil to prevent the wax from sticking. I lightly covered this with vegetable oil and took the plunge. OK, one of the petals stuck but otherwise, it looks to have turned out rather well. I hope it arrives safely.
Also on the subject of wax, I usually use a ballpoint pen for fear of the address running in the rain if I use a fountain pen. Sometimes I protected the address with sticky tape. A couple of correspondents have suggested/used candle (not lit) rubbed over the address - looks like it works nicely.
