The Rubber Band Trick - If you need to remove a nail, criss-cross a couple of rubber bands over the top of the hammer before using the hammer's claw. The rubber bands will protect the surface that you're removing the nail from.
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!!
Mark, Don't Measure - Holding trim in place and marking it is always more accurate than measuring, often faster and iteliminates mistakes. This is good advice for other types of carpentry work too, like siding, laying shingles and sometimes even framing.
I really like this idea. I have Dozens of unused eyeglass cases laying around. An unused glasses case makes a convenient storage spot for nail files, clippers and other manicure essentials while on the go.
