You have some very good options given to you here. I wish you well!
Penny's right, anything under or at the $5 mark, I think people are willing to shell out for quicker. I'm on board with the snap bags, draw string bags, the pet mats and pet coats, key chains, eyeglass holders....all of it! You'll do well.
Maybe make a few of them all and see what sells for you, and then go from there next year?
