Clever!! What a great idea to hang a picture!! Put the toothpaste where you will want the nail to go. Then, press the picture to the wall where you want to hang it so that the toothpaste from the back of your frame sticks to the wall. Why didn't I think of this? Just a great idea!!
This tip has saved my brushes many, many, times. Thanks to Laura Cox of Heart of the Home Stencils who first led me to Murphy's Oil Soap! "If you petrify a brush just soak it in Murphy's for 24 to 48 hours and it dissolves all the paint and makes it like new."
