Rotary wheel cutters are a popular alternative
to scissors. They're a particular favorite of quilters and crafters,
offering quick, accurate cutting for straight edges and multiple layers, as
well as curves.
Choosing a Blade Size
In general, the larger the rotary blade the easier it is to slice through
fabric. Smaller blades are a good choice for cutting around curves, but
cutters with larger blades will be the ones you reach for most often.
