Half Square Triangle Cushion Tutorial

 Making a Half Square Triangle Cushion

I'm a big fan of simple blocks and shapes when it comes to quilting, I like to see the print of the fabric and I like to add a solid colour to give the eye somewhere to rest and create a strong statement.

I've recently finished making 2 cushions using HST's and I thought I'd share my process with you. For both cushions I used fabric panels from my shop. You don't have to use the same prints or colours, choose something that will complement your home decor.
For the grey cushion, finishing at 15.75" (40cm) square you need to cut:

8 solid pale grey 5" squares 
4 white with cloud seed 5" squares (1 panel)
4 grey with white seed 5" squares (1 panel)

For a solid backed cushion you'll need 2 fabric panels and 1/2m pale grey coton.
In this cushion I used my printed fabrics on the cotton basecloth.


Draw a line diagonally across the solid pale grey squares and place each one directly on top of the printed sqaures, right sides together.
Using a quarter inch seam allowance, stitch on either side of the diagonal line. Cut along the line so you have two triangles. Open and press your seams to the solid pale grey fabric.

Trim off ends so you're left with neat squares.
Once you've decided on your layout, sew together each row, using half an inch seam allowance. Press the seams on each row in alternate directions to reduce the bulk.

Pin at the point where the squares are to meet and join together your rows. When you're happy your corners meet, press open the seam from the back to help reduce the bulk.
For the blue cushion, finishing at 19" (49cm) square you need to cut:

8 denim grid 6" squares  (2 panels)
8 cadet essex linen 6" squares

For a solid backed cushion you'll need 2 fabric panels and 1/2m essex linen.
For a pieced back you'll need 3 fabric panels and 1 FQ of essex linen.
In this cushion I used my printed fabrics on the linen / cotton basecloth.

The method for making up this cushion is the same. I hand quilted with a single stranded cotton and did a heavy Sashiko style running stitch on the essex linen and a lighter version on the grid print.
If you make a HST cushion or quilt with my fabrics I'd love to see, share it on Social Media with #ColetteMoscropTextiles.

Please ask if you're unsure about anything, I'm happy to help where I can.
