Hi!  

I wanted to cut fondant with my Silver Bullet but was unable to find much info out there and what is out there is mostly pretty old.  After garnering all that I could and a bit of experimentation I have found what seems to work and thought I'd share.

Just to be clear, I am an experienced paper crafter and this is just another way for me to use my machine, but you don't have to use any particular brand of cutter or be stuck using cartridges.

You will find links to videos in the blog post. I am not affiliated or paid by anyone but I use SCAL for designing (although I used to have a Cameo and used Studio, so I am familiar with that too.)
