What specialty rulers do you use?
What specialty rulers do you use and how do you use them? I only use “ordinary” square and rectangular ones, and I don’t want to have a huge collection of specialty rulers, but I do sometimes wonder if I’m missing something useful. Please post about which specialty rulers you use the most and what you use them for. Is it for a particular type of quilt, or is it for a particular thing (like making HSTs). Bonus if you post a picture of the ruler.
I don’t make enough quilts to make too many of the same design more than once, but I’d still be interested in ones where they save so much time even if you’re only going to make it once it’s worthwhile.
