The Tool That Changed Everything
Used by over 100,000 quilters and backed by Gudrun's expert tutorials, this is the ruler that helps you finish more quilts with fewer mistakes
Stripology Rulers: The Quilter's Secret Weapon
Designed by Gudrun Erla, Stripology rulers cut strips, squares, triangles, diamonds—even square up your blocks—faster and more accurately than traditional tools.
Cuts strips in seconds
No more shifting rulers or triple-checking measurements. Just line up your fabric and cut through multiple strips with one smooth motion. It’s fast, it’s easy, and yes, you’ll actually enjoy cutting.
No-slip grip for easy cutting
Slide it easily into place—then it grips exactly where you set it. The Creative Grids® non-slip grip holds firm while you cut, so your ruler won’t shift or slide mid-slice. No slipping. No frustration. Just clean, accurate cuts.
Designed by a quilter (who teaches you how to use it)
Gudrun Erla created Stripology to solve her own quilting headaches, and now she teaches you how to get the most from it. With free tutorials, project videos, and tips in every class, you’re never quilting alone.
Meet the Maker
Gudrun Erla is the designer, teacher, and creator of the Stripology ruler. Frustrated with how long cutting used to take, and how easy it was to mess up, she invented a better way. Her Stripology system has helped over 100,000 quilters save time, reduce waste, and fall in love with quilting again.
Now she’s here to help you do the same, with tools that work and tutorials that actually teach.
