Q:Gisele asked: "Can you tell me what an embossing folder is please? I have seen some beautiful Christmas cards using this and I love to make cards. "
A: An embossing folder is two pieces of plastic hinged together that have raised motifs on them. You put a piece of cardstock in between and run it through a die cut machine. Out comes the cardstock dry embossed with the motif of your embossing folder.
Check this tutorial. It shows how to emboss with an embossing folder.
