Few organization and cleaning projects feel quite so fulfilling as a yard sale. You make a major dent in your overstuffed storage, and you get paid, right? Not if you host it late on a Sunday in August, according to professional organizer Geralin Thomas. She offers up a wealth of logistical and conceptual advice on putting together a successful garage sale, including these timing tips:

1. Not every day is right for a yard sale. For example, don?t schedule your sale on a holiday weekend unless you live in a tourist town.
2. The best months for sales are April, May, June and September.
3. If possible, try to schedule your sale near the 1st or the 15th of the month because those are paydays for a lot of shoppers.
4. Saturdays are best.
5. Earlier in the day is better than later.

I can vouch for the hints about holiday weekends and early-risers—by 2PM on a Sunday, anything on your yard is probably there for good. What led to your own successful yard sales? Help your fellow would-be merchants in the comments. Photo by wonderjunkie.
