they require lots of room, strong arms to pick up/move them, steady hands to keep it from slipping(yes, the fabric can still slip), and the same precision with the rotary cutter than your regular needs!

Someone asked if a left handed person can use them, and I am sure it can be used by a left handed person. The rail that the ruler slides on on the right side can be repositioned to the left side, and they sell an ergonomic rotary cutter (which I bought) which comes in left and right handed styles. I recently bought a used Quilt cut and just haven't been home to get it set up and used yet, but I am pretty sure I am going to like using it. I know it is accurate because before I bought it I brought home a fabric square which was cut by a dealer during a demo at a quilt show. I knew what size she had cut it, and I compared it to the same size accurately cut square of fabric I made at home, and they are identical. Accuracy was my big concern, and I needed to know before taking the plunge.

Set up is super easy, you just take it out of the box and snap on the quide:D
