Necessity is the mother of invention, as the saying goes. In my home we have an attic with pull down stairs, and it seems that the string is always just out of my reach. So instead of pulling out my step stool every time, I get spaghetti serving spoon (funny looking spoon with tines and a hole in the middle) out of the drawer and use that to grab the string.
It works great, saves time because I don't need to call my husband or get a step stool, and it's another way to utilize a tool that's already around the house! I got my spoon at Target for around $5.
