Then you need to cut out 3 pieces of material. This coat hanger was 13" wide so I cut a backing piece 2" wider at 15" x 15". The second top front piece was 15"x 5". The third bottom front piece was 15" x 11".(This last piece will be covered with stitch and flip so only needs to be a scrap like left over curtain lining).
Next cut some strips of varied widths from any fabrics you fancy and play about with them until you like the effect.
Keep going until you cover the whole of the front bottom piece. Zig zag along top edge and turn under about 1/2".Sew. Also hem bottom edge of top front strip and embroider or add any 'frills' eg ricrac.
Next place backing fabric right side up on table. Then place front top and front bottom pieces on top of the backing piece, right sides down. Use coat hanger to mark gap to be left in upper edge for the neck of the hanger (3" in this case). Pin and sew around the perimeter of the square about 1/2" from the edge leaving the marked gap. You can also zigzag edges to neaten and hold if you want/can be bothered!!
