Gadgets are awesome! I got the Restring It package last week and put it to the test. Lucky for me, I had a pair of sweatpants that always loses the drawstring in the wash.
This tool has and end to grab the string and a long flexible body and then another long needle at the other end. Works like a charm is and is the newest member of my laundry room staples!
