How to make the Half Square Triangles (HST)

Watch the 2 minute video tutorial on making 8 HSTs at once:

Some notes on making the blocks

Fabric needs

Each pair of 7 inch squares makes 8 HST.

You will need at least four 7 inch squares for each block or more for blocks in 3 or 4 different fabrics. The left over HSTs will be used in the sashing.

I give you the fabric needs for each block tutorial below.

Trimming half square triangles: Essential. Remember to trim off your HSTs  and make sure that they are 3 inch square.

This quilt is fat quarter friendly.

Colour scheme: For better results, use high contrasting fabrics.

Free motion quilting

Once you make the 16 blocks, it’s time to quilt them individually before you put them together with quilt as you go.

Quilt-as-you-go (QAYG) with 2 inch sashing tutorial

Learn to how to quilt as you go with sashing in just over 3 minutes:

Sashing mini hourglass blocks

The long sashing strip for the back has hourglass little blocks in the intersections.

I used the left over HSTs from the blocks to make an hourglass block.

To make the hourglass block, take 2 HSTs.

Quilt as you go, sashing of the quilt back

Place both HST with right sides facing together as shown below:

Sew together on  each side of the diagonal line, at 1/4 inch from the line, as shown below:

Making the binding this way is so fast… I don’t think I can go back to hand sewing the binding after this.
