Today I've included some quite old pictures of the early days of my felting experiments using a resist to create 3-D vessels and bags. In this method the wool fibres are laid out enclosing a plastic template of the required size and shape. The felting and part of the fulling process takes place with the plastic in situ. As the felt begins to shrink around the template, the felt is cut to release the plastic and the energetic fulling and shrinking continues!
I learnt the technique from books, so it did take one or two frustratingly unsuccessful attempts before I discovered some of the do's and don'ts! There were bulky lumps at the edges where the fibre layers were too thickly overlapped and unnecessarily large holes cut to remove the template, but I think now I understand what's needed, even if I don't always achieve it in practice!
