I use Quilter's Select rotary cutter. I have a Gingher one too and a Tulip Pink one. Lots of Olfa ones in different colors. I like the Quilter's Select best. I have three of those. Every time I go to Paducah quilt showI buy the Quilter's Select Special box for $99 that has the rotary cutter, thread, QS ruler, mat etc.
