The multi–striped fish features the reverse appliqué technique. This is detailed in the Reverse Appliqué Tutorial. I have used strips of various coloured fabrics for the fish. The crystal organza fabric was placed on top. All the layers of fabrics were then stitched together by couching lengths of knitting yarn using a zig-zag stitch. The top layer, which is the crystal organza, was then carefully cut away between the couched rows to reveal the coloured fabric beneath. Choose where to cut according to your interest.
