Your local craft and sewing stores would be worth a look. They will almost always carry small crochet hooks.
Another option for you would be to buy one of those pre-loaded visa cards from a grocery store. You just use cash to put some money on it, you can use it once and throw it away! It won’t be tied to any of your accounts or anything. 🙂
(remember that at dreadlockinfo we give hair advice, not financial advice, so take that advice up there with a big ol pinch of salt!)
I hope this is helpful to you!
