There is a product available but not in the annual or the holiday catalog. It is a product that is designed to make embossing a little easier as Stampin' Up! goes through the change from the BIG SHOT to the replacement embossing and die-cutting machine. I do not have any new news about the replacement machine but recently the flyer, below, and the product have been made available. Sorry it's a little creased ~ I have been using it all month in my stamp club classes.
The plate is designed to work with the new-style 3D folders which are thinner than the previous folders labeled 3D. You can see the current 3D embossing folders on page 199 in Stampin' Up!'s annual catalog. And, the Hammered Metal 3D embossing folder on page 31 in the Holiday Catalog. You will not need to add shims as we have in the past and you will only need ONE plate. The new blue 3D EMBOSSING FOLDER PLATE, # 149658, is $10 and it will make your life easier! Let me know if you have questions.
