One of our most favourite rulers here at Hamel’s is Quilt in a Day’s Triangle Square Up Ruler. When students take our Beginner Sampler class, this ruler is required. Think about all the quilt blocks out there that require half square triangles!
The 6 1/2 Triangle Square Up Ruler makes perfect half triangle squares and quarter triangle squares in sizes up to 6 1/2″. Fully illustrated and detailed instructions are included when you purchase this ruler. The ruler is marked in two colors for easy reading. Convenient 1/8″, 1/4″, 1/2″ and 1″ lines for precise measuring. The ruler is made of heavy gauge acrylic and is laser precise.
Want even a bigger ruler? Well, you can also special order the 9 1/2” version of this ruler.
Here’s a video demonstration with Eleanor Burns of “Quilt in a Day” using this ruler to create perfect half square triangles. Even tho this video is a “few years old”, the technique still works today and we recommend it.
