Sometimes I use a stamp, but this was my experiment embossing my own handwriting using Ranger "emboss it" pens
I used three different embossing powders (silver, white and bronze)
I like the fact that no two are exactly the same.
I was going to write a how-to post, but besotted blog has two excellent embossing tutorials to get you started:
