Help! How do I line a felted bag?

Hi,

I’m a relatively new knitter and am well into knitting my first felted tote. :happydance:
I would prefer to line it, but have no idea how or what fabric to choose. I don’t own a sewing machine but am reasonably competent with a needle and thread.

Do you know of an online tutorial or some information about it that can help me?

Thank you much!

Here are three links that I’ve used before…

one

two

three (password is knittinghelp if it asks for one)

Thank you Sara! All three are excellent and suit my purpose very well.
