A couple of weeks ago I was about to order a cuttlebug as I loved the embossing folders. I was told that the folders worked in a Sizzix machine so I decided to experiment. I found a book that was just deep enough to squeeze through the machine although I also added a sheet of funky foam as I wanted slightly more depth to the embossing. I sandwiched the embossing folder between the funky foam and the book on top of the cutting mat. As you can see it works pretty well! I think the system converter works with them but if like me you don't have one then a book does fine!
This calls for more shopping I think!
