How to make half square triangles using a grid video tutorial

Half square triangles (HST) are basic shapes in quilting. You can make full quilts using just HSTs.

They can be made with different techniques: the traditional two at a time, 8 at a time, and my favourite and flexible way to make any amount of HSTs you like at once.

Today’s video demonstrates how to make HSTs using a grid.

For today’s block we need 12 HSTs so I made a grid 2 H x 3 W. This translates to 2 x 4″ = 8″ and 3 x 4″ = 12″.

So cut 2 pieces 8″ x 12″ in contrasting fabrics and get going! I added 1/2″ to each measure – I prefer trimming than being short.

Finished HST size: 3 1/2″ x 3 1/2″

Starting squares: 4″ x 4″
