This is a Paper Stump or a Paper Thumb. Some people call it other names too. They come in a variety of sizes. My favorite is size #8. It's easy to hold and works well for most tight spots. But I do own a bunch of the other sizes too. If you own a paper stump (they are also used by charcoal artists for blending), a mousepad and an empty ball point pen... you can metal emboss! Of course, it's nice to have all the tools and the work is much easier with all the tools but if you aren't sure if you are going to like it, this is an easy, fast and inexpensive way to get started! Oh and you'll need some metal. :-)
So, I decided to try my hand at the exact same design that Magdelena did:
And this one is on clear acetate and has a nifty technique on the back! Fill the embossed area with spackle, let dry and then use alcohol inks right over the whole thing! You'll color your metal AND the spackle, leaving you with this...
Pretty neat, huh? The spackle is more of a burgandy in person so the effect is stunning. And a surprise when you open the card!
I hope you enjoy!
