WHAT YOU'LL NEED:
Step 1. Lay out fabric on the fold.
Step 2. Using a tape measure draw out a square that is 67cm by 67cm. This will include your 1cm seam allowance so the finished cushion size will be 65cm x 65cm.
Step 3. Over lock or zig zag stitch around both squares of fabric.
Step 4. Insert invisible zip, and turn cushion inside out so right sides are facing each other and leave the zip a little open to allow for turning back through.
Step 5. With front and back right sides facing, pin together around the edges. Make sure the zipper is open a little for turning through. Sew together around remaining 3 sides using a 1cm seam allowance.
Step 6. Snip across corners to create a clean point when turning inside out.
Step 7. Turn pillow inside out and fill with insert.
Step 8. Repeat process for other colours.
