I admit, I am a ruler and gadget junkie. I have the QCR and the longarm ruler that goes with it. Love them both. There is a learning curve, but once you watch the videos a few times, it isn't so hard to follow their patterns. The first quilt I made with the ruler I used my normal 45mm rotary cutter and it was okay but then I realized that a 28mm works much better on those curves. I'm working on my third Sewkindofwonderful pattern now, Metro Medallion. You can't speed through these patterns but I love a challenge.
