Notion of the Month: Half Square Triangles

It’s Notion of the Month time! This month we have selected Half Square Triangle Paper as our Notion of the Month.

Melissa from the Sew Bitter Sweet Designs blog (originally from the Love Affair with My Brother blog) is going show us how easy it is to use the Half Square Triangle Paper.

And don’t forget the Notion of the Month is 20% OFF all month!

Hello! I’m Melissa from Sew Bitter Sweet Designs. I’m here to show you how to use HST (Half Square Triangle) Papers. I love this method! I made 20 HSTs in 20 minutes – and I didn’t have to draw a SINGLE LINE!

These are one of my favorite new quilting tools – they make sewing HSTs quick, easy and painless!

You will need the HST size paper of your choice – I am using the 3″ finished HST papers here.  Select two different fabrics and cut your fabrics slightly wider than your HST paper.

I wanted to make 20 HSTs, so I cut 5 squares long by 2 wide on the paper roll. With your fabric right sides together (RST), pin the paper on top.

Follow the arrows and sew along the dashed lines.

Use your rotary cutter and a ruler – cut along the solid lines.

Tear off the paper, press your seams open, and remove the dog ears.

There is virtually NO waste using this method – I made 20 HSTs and the vast majority of the waste was the dog ears.

I arranged by HSTs to make this beautiful 12″ square – use a 1/4″ seam when sewing this block.

Do you like my fabric? It is Ruby by Bonnie & Camille.

Giveaway coming to my blog soon for Triangle paper – stay tuned!
