MapedHelix USA Circle Ruler, 12-Inch, Color May Vary, Assorted Colors (36001) by Maped

I was a bit disappointed that the plastic is so thin but it does the job ok.

I love water painting landscapes and outer space/night skies… but I can never draw a perfect circle, let alone several. This shows you the exact sizes you’re drawing, so you can easily create perception or (at least slightly) more accurate depictions of planets’ sizes in comparison to each other. The additional feature of it being a ruler is SO useful for adding borders or zodiac stuff and alignment paintings. The ruler is also super useful for landscape paintings - definitely helps with perspective!! Excellent value for the money; excellent ruler for artists, quilters (appliqué!), students, and everyone - great to have on hand!!

LOVE this gadget. So easy to use for designing circles for calligraphy.

great works well

Coming from a graphic designer, this is one of the best circle makers available. It features a simple, straightforward design. Compasses are great, but sometimes you need something quicker. Also, a compass can’t create the small circles that the stencil on this ruler can. I’ve tried many so called “top of the line” circle makers out there — but they all prove gimmicky (at best). Maped brand is the way to go. The only thing I would improve on is the flimsiness. This baby could snap right in half if you’re not careful. Wish they made one in stainless steel. Overall, great purchase.

Works well, I would buy another one
