Our church has an excellent solution for that. Every spring, usually early April, we have what we call Spring Exchange. During every service in March we are allowed to bring in things we no longer want. You usually see people coming to church carting a great big trash bag full. We bring in every kind of things from clothing to housewares to toys, books, well you get the picture. Then on Thursday and Friday before Spring Exchange day the ladies of the church go through every thing and organize. We use all of our Sunday School rooms with different categories in each, i.e., kitchen in one, children's clothes in one, toys & books in one, ladies clothes in one, men's clothes in one, etc. The ladies and mens clothes are all hung on hangars by approximate size. It is very neatly organized.
Then on that Saturday, any and all of our church people can come in, church attenders and needy people who are brought by church people. It is emphasized that you don't have to donate to come and receive. At the door as you enter they give you a great big trash bag, you go through the rooms and take what you need - no charge on anything, which is why we call it the Spring Exchange. This is great if you have gained or lost weight, too. We all know not to bring in junky stuff, just things we no longer want, but that someone else might want. Works great.
