I am a new quilter being guided by my sister, an experienced quilter. I use the June Taylor ruler and love it. I wouldn't cut strips any other way.
However, my sister also had me buy a suction cup type holder that sticks to the ruler. It allows me to push down on a handle type thing instead of just on the ruler. The first one she bought was from a quilting store and cost $25. Then we found them at Harbor Freight for $7. (I think that was the price.) Someone out there is going to know what it is called, but I have also seen it at Linen & Things, for a higher price.
It is designed to attach to the side of a shower to help get in and out of the shower safely. It has strong suction cups on each end of the handle and secures itself easily. Harbor Freight also has two mini versions that I bought.
Hope this helps? Like I said, I am still a beginner.
