From Knitty Gritty’s Real Men Knit: Felted Messenger Bag:
episode DKNG-709

“This project is great for the man who knits, but women will enjoy it too.”

“Stephen Houghton, an avid biker and the creator of hizknits.com, shows how to create a felted messenger bag complete with an inner-tube strap. This bag is knit in the round and the tube is knitted into the bag itself, which makes it truly secure. It’s functional and fashionable and appealing to everyone.”
