I took Teri Berry’s excellent wet felted bag class recently. One project was a backpack. The shape and colours are my design; all the construction and know-how are Teri’s.
It took a lot of hard work but I managed to get it really firmly felted so it’s very robust. This is Corriedale wool which again should make sure it’s good and strong and won’t pill to much. One thing I hadn’t thought about: the shape fits really well into the curve of my back which feels very comfortable but is quite warm.
