Cuttlebug cuts cleanly as Sizzix dies. =) But, since it's a thinner die, you may need to use a shim (thicker shim) or a converter. Most of my dies consist of Cuttlebug & Sizzix. (yeah, once upon a time, I was addicted to buying dies..lol..)
But, since your question if it'll work on Big Shot, I will try it (Cuttlebug) on my Big Shot machine and see how it goes. I had no problem using Cuttlebugs using on my Sizzix Original.
Bear in mind that I only use blended or 100% wool felt. Absolutely no craft felts (HL/Michael's...)
How well do cuttlebugs die work with the sizzix big shot/big kick? I love the variety they have but I am afraid they won't cut well. Thanks in advance!
