These beautifully made, soft genuine leather project bags are absolutely gorgeous, and big enough for a sweater size project.
There is a zip on the one side to pop notions into, and 2x eyelits to feed your yarn through if you wish. The bag has one, solid strap which fits over your arm so you can knit/crochet on the move (if that’s your vibe!), and the bag boxes out to sit nicely when it has your yarn and WIP in it.
