This is a great technique to add variety to your embossing. You can use any type of adhesive that will give you the look you want. I like to use sticky tape since this is something I can demonstrate in my classes. I have used it as a replacement for ribbon on my cards. Place the adhesive onto your card stock wherever you'd like to emboss. Then sprinkle embossing powder on the tape. Heat to melt the embossing powder. You'll see amazing results.
