I am thinking about taking up crochet as a hobby.  Do you crochet?
I do not crochet.
Do you know if it is hard to learn?
I am not sure but all you need is fabric to interlock with yarn.
What kind of fabric is used and how do I interlock it?
You have to use a small hook. That is what the term crochet means in French.
I didn't know it was French!  Is the hook the long needle thing?
They are made from metal,wood or plastic. Not sure of the size.
