Chalk: To prevent tarnish or if you have a small area where dampness is causing problems, grab some chalk and tie together with a cute ribbon and place the chalk in the area... it will help absorb moisture.
Felt and rubber bands: Place at the end of a hanger to help prevent your delicates from sliding off the hanger. You can also wrap rubber bands on the end of the hanger to also prevent your delicates from sliding off.
Plastic wrap: Need a quick rope or something to hold a stack of slippery items together? Wrap in plastic wrap or take a long sheet and twist together to make a quick rope!
