I would have to say rotary cutters because scissors hurt my hands.(arthritis)

i could not live without my rotary cutter, mat, and fluorescent ruler

The Cutting Gizmo. You set it to the left of your sewing machine. It has a razor blade inside of it and when you chain piece, you lay the pieces down on it and it cuts them apart. Voile!!

All the plastic we have for templates and rulers instead of having to make them.
The TruCut rulers with their matching ergonomic rotary cutter
The TruCut electric rotary blade sharpener.
Nifty Notions half and quarter square rulers
Deb Tucker's templates

Love the clover clips but also love my turning mat it sure helps when cutting pieces that need to be turned and cut more than once.
But my all time favorite is Quilt In A Days triangle square up ruler where you sq up with one cut. It is amazing.

Seems you all are in love with this spray, i think ill need to try some.
Im in love with my rotary cutting syztem. I saw it when it first came out,
Splurged and never turned back.

I have the Cutting Gizmo too. How do you keep it from sliding and keep it in one place? The little stinker keeps skidding away on me.
