These are examples of what you can do with .003 copper sheeting glued to cardstock using spray adhesive. Generally, you can use the copper-covered stock just like you use cardstock. For the hearts, I cut out the hearts and then used embossing folders to add designs. You can see that the cuts can be very elaborate (the corset). I often use copper for word die cuts. Be careful when smoothing or working with the sheeting, it will scratch and dent. I use a file folder taped around a few layers of sheet packing foam. The copper can be etched, aged, or polished depending on the project. Endless possibilities. I like the shiney stuff myself.
