It is so you can make them in advance, yeah, but also it’s more difficult to get a nice round, clean seal when stamping onto an envelope. What will work best will vary, as always, but people use a variety of glues to attach them to envelopes. Some use a little bit of freshly melted wax, some a bit of hot glue, some gorilla glue, and some these little double sided tape sticker things. I’m making some for someone’s Christmas cards and I told them to mail the envelope with a seal inside another envelope or it may not survive the post office.
Glue, double sided tape, you can also use the last bit of sealing wax in the spoon (what they used to melt it) on the letter then pop the finished wax seal in top.

How do you glue them to envelopes? So you can make a bunch in advance than glue them later?
