A Swiffer Sweeper floor mop is useful for more than just cleaning hard floors. Use it to dust interior walls and trim, too! Attach a dry cloth to the rectangle end and press it along walls and trim.
If you find your fitted sheets slipping off the corners of your bed, look no further than your closet for an easy fix. Just use a pair of elastic suspenders, clipping one end to each corner under the mattress, and your sheet will stay put.
Garage floors are puddle prone: springtime floods, melting ice from tires, you name it. You can keep that water away from your tools and toys with a dam made of expanding foam.
Instead of picking a hobby that you're already skilled at or one that's impossible to master, pick something you feel confident you can see major improvement with.
