Yarn people - a question

[Renthead Mommy]

I want to crochet small bags that you put the soap slivers into.  Then you can rub the bag, which rubs the various soap slivers in the bag.  And it will hang in the shower. 

 

I have my great grandmother's crochet hooks that start as small as toothpicks up to regular J/K sized ones.  I am thinking I want to use the tiny or at least the smaller hooks.  What yarn/string/? do I use with those?  And these are to be hanging in a shower as well.

 

Suggestions please?

 

Thank you.

I would use a cotton yarn like this:

These are sturdy yarns and will hold up to scrubbing.

 

Lots of pattens I see suggest using an H hook.
