Anything you can do when hosting a yard sale to make customers more comfortable while browsing will bring you more success. A great idea is to place a group of similar items under a canopy. Set up tables so that your customers won't have to bend over to inspect your items, and arrange the items atractively. The canopy will make people more likely to spend a few extra minutes outside of the scorching heat or the rain and looking through your well-organized items. Those few extra minutes may be all it takes for them to find something they have to have.
