I encourage you to create a donation bag and keep it centrally located in your home. The front hall closet, the laundry room, or in the garage are all possible places for the family donations bag. Once everyone knows where to put the clothes that don¹t fit, the books they have read, or the toys they no longer play with, the donation bag will fill up quickly. When it is full, put it in your car to be dropped off at the nearest donation center, church or homeless shelter so that others may benefit from the items that you no longer need.
