1. Draw the outlines of the key elements of your design on a piece of paper the same size as the finished block. Pin the background fabric onto the paper. Tape to a window if this helps you see the design on the paper. You will use the paper to align the details of your design.
2. Draw the details of your design onto fusible webbing such as Bondaweb or Steam-a-seam but remember that these images will come out in reverse on the final block.
3. Number the segments of your design and cut out. If the design is very complicated, cut out as you go so you do not lose track of where you are.
4. Fuse each piece of fusible webbing to the back of the pieces of fabric you have chosen for your design. Once fused, cut out the shape but take a slither off the edge of the paper. I don't mean an 1/8 or an inch, I mean a real slither, like a millimetre or two.
5. Place onto the background fabric leaving a small gap between each piece but do not fuse into place until the section you are working on is all in place and lined up. Remember you are going for a scrappy look here so don't worry about perfect lining up - for this job, perfection is not required.
6. Once all pieces are lined up, fuse and then edge with the stitch of your choice. I chose blanket stitch on the flowers and straight stitch on the rainbow tree.
