We recommended the use of Fast2Fuse for the bowls, but had some trouble bonding the fabric to it. We came to the conclusion that the irons were perhaps not powerful enough. The use of steam seemed to help. The instructions have been amended to reflect this. There were two styles of bowl to try, one a hexagon using cut darts and the other a round bowl using overlapping darts. They both involved a lot of satin stitching, it can be difficult to achieve a neat finish, unless you alter the top tension. Participants were encouraged to test out the satin stitch on their machines, using the 'fabric sandwich' scraps left over after cutting the bowl shape. If you use a dark fabric the white stiffener can show through even after 3 passes with satin stitch around the edge. It may be of benefit to colour the white edge with permanent marker of a suitable colour before you do the satin stitch on the top edge.
This workshop was a great success, as everyone had a complete bowl at the end of the 4 hour workshop. Our most annoying problem was with the bonding of fabric to the interfacing, it took longer than anticipated and required reinforcing at intervals with a bit more steam.
The instructions can be found below and on the patterns page of the website. You will have to make your own patterns, instructions for making a hexagon are included.
