My mom went to Scotland a few years ago, and brought back scarves that were knit with the buchanan tartan (My family's Tartan), Unfortunately my sisters scarf ended up in the wash and because it is wool it felted and shrunk which made it kind of not usable as a scarf. So I redid it into a wristlet purse for Christmas for my sister.
This is a modified, simplified version of the link provided. I didnt add a liner because the felted wool was really thick and with a liner it wouldnt go through my sewing machine. Its really heavy duty though, my sister will have a hard time ruining this purse.
