Step 4

How to make a rainbow shaped cushion step 1
Lay out one of the backing pieces and lay the outer arc piece on top, right side (RS) together. Set aside for now.

Step 5

Take the centre and lower arc pieces and snip approx 7-8mm in at roughly 2-3cm (¾-1¼in) intervals around the curved part of their edges only.

Lay the centre arc piece RS down on your work surface. Along the outer edge (but not the straight bottom edge), fold the fabric in by 1cm (3/8in) and press as you go around

Step 6

Lay the centre arc piece RS down on your work surface. Along the outer edge (but not the straight bottom edge), fold the fabric in by 1cm (38in) and press as you go around. Do the same with the lower arc piece.

Assembling the front panel

Step 7

Turn the centre arc piece over so it is RS up and the folded edge is underneath. Place it on top of the outer arc/backing piece so that the bottom edges align and the sides of the blue piece are 10cm (4in) in from the edges of the outer arc piece. Pin around the edge of the centre arc piece (you don’t need to pin along the straight bottom edge). Repeat with the lower arc piece, making sure the sides are 9cm (358in) in from the sides of the centre arc.
