My rotary cutter, cutting pad, and ruler are always on the table beside my sewing machine. I enjoy good scissors and have three or four seam rippers, but I use the rotary cutter all the time, to trim seams, to trim threads, to cut some patterns, etc. My last project was covers for my small kitchen appliances. Measure the appliance, rotary cut the pieces,
serge them together, and presto! A new look for the kitchen!

That looks like my ruffler. It's a great attachment if you ever do ruffles.
