This is a good project for using your left over yarn. You could probably use any type of yarn with any sized hook - as long as you keep your stitches tight.

It’s a fun way to keep your things nice and tidy.

After a few requests, I have started making a video tutorial for these. Please bare with me as it will take me some time. I will post it to my blog once it’s done. Thanks for your patience!

Turns out making a video tutorial is very time consuming and I haven’t been able to get it done. But I have been able to make a photo tutorial for the set up of the case. Find it here: http://peneknitcrochet.blogspot.com.au/2013/08/hook-monst...
