Several years ago, I won a trip to a major quilt show that included $200 cash. I purchased a Martelli mat, rotary cutter & strip cutter. Still have the mat - I use it as a measuring stick under my Olfa mat. Gave the rotary cutter & strip cutter away. Also have the useless lighted seam ripper. Those are just a few of my regretted purchases but will probably fall for something else in the future. What can I say, I'm a gadget girl!
