Rubberband
No one wants to spend all that money to hire a professional painter when they can do it themselves. However, the main problem is when you get paint all over and your brush is soaked in paint. Use this trick: wrap a rubber band around the paint can and use it to get the excess paint off of the brush and keep the edges of the can from getting dirty.
Straws
Straws are the answer to tangled jewelry. To keep necklaces from getting all tangled, thread their chains through a straw and clasp them that way. Keep them in your suitcase when traveling and watch how much neater it will be.
