Heheh.. bags are fun but putting them into a box works too! Yes, I am intrigued by @akippon's bags too :) She gives a lot of thought into her bags and it makes sense too with groceries. I think these net bags are fun to make because it works very quickly. You can probably whip up one in an hour :)
Oh and that crochet hook is very cheap, about 2 dollars. I got it from Daiso, a Japanese chain store that sells things at about 2 dollars an item :D
