What do you need for a garage sale?

You need plenty of stick on tags for pricing, signs to put up on visible street corners near you. Tables to display items, these can be made from sawhorses and a board if necessary. You may also want a rod of somekind to hang clothes on that you want to sell. I do not price all clothes separately. It is easier to just put up a sign that says tops for this price, jeans are this much etc. Just generalize and it will even out if some may be nicer than others. And one of the main things you need is an ad in a local paper. Allow plenty of time to prepare for it or it can get stressful.
