Why quilters switch to Stripology

Line up once and cut up to eight 2-1/2" strips without moving the ruler.

No more slipping rulers, crooked strips or re-measuring after every cut. The slits are built in, so cutting goes up to 75% faster, and one ruler replaces most of the ones in your drawer.

The XL comes with illustrated step-by-step instructions and a QR code to the how-to video.

The rulers have totally transformed quilting for me and made it so much easier and quicker.

I was cutting 5” and 2.5” squares and it took me roughly 2 hours vs a couple of days.

In a matter of minutes I had cut 200 squares and the accuracy and lack of waste just blew me away!

This makes the boring task of cutting quilt fabric a breeze. … It took me about 20 minutes to cut ALL of the fabric accurately.

The story

Gudrun Erla grew up in Selfoss, Iceland, taught PE, and found quilting at 23. In 2000 she opened Bót.is, Iceland's first online quilt shop, with weekly classes and a club of more than 250 quilters from across the country.

Her customers wanted patterns, so she wrote them in Icelandic. Soon she was selling them in the US, and in 2003 the family moved to Minnesota.

Gudrun thinks and designs geometrically, from the ruler out. That way of cutting became Stripology, and she unveiled the first Stripology ruler at a quilt trade show in Houston. It hit the market in 2014.

One ruler grew into a whole way of quilting: four rulers, the books and patterns built around them, kits and a case to carry it all, a certification course for Stripology instructors, and partner shops that teach it. Gudrun has taught it across the US, in Canada, in Iceland and all over Europe, and today she teaches quilters around the world online, in virtual retreats and live shows.
