BUG USERS!?! THAT'S RIGHT.......OKIE DOES!!
I was able to manage to get the Tri-Shutter GBS card .cut file made. Now let me tell you this sucker is a little tempermental so I don't suggest moving anything on the card base around or ya might get the DREADED RED X OF DEATH! *okie knows from experience*. It will only cut one card at a time but at least ya don't have to do all that stinking measuring. The instructions will be the same as the Plantin version.
**WARNING** I did not do a test cut on this file because I don't have my baby bug hooked up. So whoever uses it please let me know if it is working okay!
