Husband and wife team, Paul and Janna Thomas co-founded Bloc Loc. Paul, an Australian, was an aircraft maintenance engineer and Janna, an American, is the author of Courtship Quilts; Inspired by the Victorian Language of Flowers, published by Martingale & Co 2005.  Janna is a passionate quilt designer.

Now based in Loveland Colorado, Bloc Loc manufactures, distributes and sells their own patent pending products which are new and innovative, made of the highest quality materials by the old fashioned standard of making products which are built tough enough to last from one generation to the next.

In everything they do, they honor quilt making’s rich role in cultures throughout the world.


We love to solve problems. Each and every BlocLoc innovation is born from the need for an easier, safer and more efficient way to create beautiful quilts.

This is so awesome! The ruler locks into position and will not move or rock!  

Because of the design of the ruler, you can turn the HST and the ruler at the same time with no slipping.  I love it!

As a quilting teacher, I try out a lot of new products–this is the best one yet!

I’ve just squared up 3 dozen HST’S in about 15 minutes and they are perfect–this is the greatest!
