- Mark everything with a clearly written price: We hate stopping by stoop sales where there's no price to be found. Pricing items will make your "customers" feel more comfortable.
- Keep everything visible: People want to see what you're selling in a glance so put it all out on display, not stacked in boxes.
- Organize: When you do get everything displayed, make sure it's sorted: housewares with housewares, jewelry with jewelry, etc.
