I love, love, love my Shape Cut Plus. It makes such accurate cuts--- no more mistakes from slipping rulers or misreading numbers. I mark the increments for my cuts with sticky note arrows.
I recently bought the Pro and a smaller one that is meant for fringing rag blocks. I thought I needed a bigger and smaller version, but I'm not so sure they're necessary. Last week I pulled out the Pro for cutting 60" sashings. It didn't have the markings I needed. I could do the math for the first one, but had to move the fabric for the subsequent cuts. Also, it is huge, which presents a storage problem.
If June Tailor would make a Pro with the Shape Cut Plus markings, I would love it.
