STEP 1 Cut two 37cm diameter circles from fabric for cushion front and back. Zigzag stitch around all edges. Cut one 8 x 126cm strip for cushion wall panel.
STEP 2 Leaving 10cm at the beginning unsewn and with right sides together, join the wall panel to cushion back with a 2cm seam (long edge to round edge). Gently ease the fabric and follow the curve as you go around. Leave another 10cm unsewn at the end.
STEP 3 Measure and mark join for the wall panel, then sew these 2 short sides together. Finish sewing the cushion back and wall panel.
