I went the easy route and bought the adapter from Accuquilt. It wasn't cheap, but I knew I was getting what I needed. I use it, the Accuquilt die, fabric and the Accuquilt mat. I don't mix and match my mats--it might be ok, but I don't want to take any chances on ruining my Accuquilt dies. I have bought some Studio dies and don't have to use the adapter with them, they cut just fine as it is. I haven't used any Sizzix dies with it yet.
