Review: Omnigrip Non-Slip Quilting Ruler: Essential Tool for Crafts and Product Photography - I absolutely love this Omnigrip square ruler, though I must confess, I don't use it for its intended purpose of quilting! For anyone looking for a reliable, perfectly gridded surface to serve as a background for scale and context in product photography, this is an absolute must-buy. I place the ruler flat in my light box setups, and it instantly provides a clean, professional ruler display right under the item I'm photographing. The 1/2-inch measurements and cross-lines provide excellent, immediate scale for small products, giving every photo an elevated, clear, and informative edge. Compared to other ruler brands I've tried, Omnigrid is, in my opinion, clearly superior. The primary reason is the exceptional ease of reading the markings. The lines are crisp, dark, and the numbers are highly visible, which is crucial when photographing it under studio lighting. I have several different sizes of these rulers and use them consistently across various light box dimensions. The non-slip backing also ensures that once it's placed in the box, it stays perfectly flat and won't shift while I adjust the items on top of it. Whether you're a quilter or, like me, someone needing a high-quality, readable, non-slip reference grid for display and photography, the Omnigrip ruler is worth every penny. It's a fantastic, versatile tool that holds up incredibly well to constant use
Review: 👍 Good for basic FREEHAND - Nice product, would not use for high tolerance work like… let’s say ‘aviation’ parts design. I received the quality I was expecting for it’s ease of use in a ‘FREEHAND’ drafting setting. Not the fine CNC work I have programmed to the 1000th of an inch or finer.👍

- Non-slip ruler with 1/2 inch seam allowances
- Made from durable, premium quality acrylic plastic
- Designed with markings for left and right handed users

### ⭐⭐⭐⭐⭐ Perfect ruler for cutting long strips
*by L***. on February 23, 2025*

You're so worse and quilters will know how frustrated is to have a ruler that's not long enough you have to keep moving the ruler from one side to the other to cut a long strip . The only problem was when I decided to get one everybody else had the same idea they're sold out everywhere Amazon's the only one that has them and they were perfectly they were a little bit pricey but not bad. Perfect for what I needed the size is great you can see through it accurate long strip cuts finally. Yes it is very easy to use and accurate
