In order to use a rotary cutter properly, you need to have a self-healing cutting mat. See cutting mat .
An example of a cutting board for fabric is shown below. This board measures 11 inches by 17 inches and is quite popular among quilters. A larger board is nice (and more expensive!). Cutting long strips of fabric on a board smaller than the one pictured below would be cumbersome.
