Recently I watched Crusade: A March Through Time - cheesy movie with great costumes, and I got inspired by the bag one of the main characters was carrying.
Look at how perfectly fluffy and large it is!
Here's a shot of a part of half-ready bag of my own. I'm using Islandic Wool, which felts beautifully, - exactly what i need to bring all of the fibers closer together to make the bag strong and shapely. I am to wet felt it, after it's finished, for sure.
