There is more than one way to emboss handmade paper First I will talk about found construction objects , cut the sheet just larger than the paper sheet , once the pulp is flipped on to the felt simply lay the wire over the paper cover with a couple of layers of felt , you can then continue your stack I found it better not to emboss two sheets in a row without several layers between . The wire goes in the press with the stack this makes a very deep impression .
If you have something you want to emboss on a sheet of finished paper , lets say a cermic flower , it has to be fairly flat , lay the paper over the figurine and cover with a damp tea towel. weight with a heavy book and leave for about 36 hours.
Also there are the folders and plates that can be purchased and run through an embossing machine
