A short time ago I asked for recommendations for rulers that don't slip. Thank you all for responding. The brand that came up most often was Quilters Select
Prices seem higher than other options and can't be found on Amazon....which is too bad as the shipping for this one was $10...price of ruler $25. A hefty investment (though it was a birthday gift...thank you Christopher). Yet for a tool that is used as often as we use this kind, it's worth it.
It truly did not slip and I really liked the marking measurement system. At first I was a bit skeptical about the rather 'frosted' look....as I was used to clear plastic rulers. However, it actually helped removed glare which I experience because of the overhead lights above my cutting table.Now I'm going to want a few other sizes that I use the most such as a big square!
