Amber goes Green - Dryer ball set
Wool dryer balls really do work:
Speeds up drying time (about 15min for a load of sheets)
Lowers static cling
Replaces fabric softener or dryer sheet
Instructions: Leave 2-3 balls in dryer all the time. Can be used for all drying requirements. Will last for about 3 years. At that point you will be able to see parts of the sweater core.
