Cheery Lynn Designs has 6 x 8 embossing plates, actual embossed area is 5 7/8 x 7 7/8. That means you can emboss a background for a 6" square card without having a seam. My card uses the fabulous Poinsettia embossing plate. These are heavy duty metal embossing plates.
I began by rubbing rose ink all over the die. Because it is metal, you don't have to worry about the ink getting in the recessed areas as the die does not bend like plastic ones. Then using a piece of Stardreams Opal text weight paper, I embossed it using my Cuttlebug. There are two great things about using text weight paper for embossing; one, you get a really detailed embossing, two, it keeps the weight of the card down. Finished size is 5.5" square.
