Fixed mistake: after your first round stitches are 58, not 30!

What can you do with a 3.5oz / 100g superbulky cotton yarn?
A little market bag!

I think that in this case plant fibers are better than animal ones; so I designed this market bag in order to use a specific handspun bamboo skein, but first I tested it with a very thick cotton yarn.

Have fun!
