It's a rite of passage when you finally get your own place; you don't have to share a bathroom, living room or kitchen space with anyone but yourself. It is great to have a place to call your own, but you will find that your own space means a few added responsibilities. While most landlords will come do fixes in an apartment or rental unit, you might want to tackle a few projects instead of waiting for someone else to stop by. Likewise, you will need at least a few tools to get your apartment decorated to your taste.
If you want to hang a few pictures, then you will need a basic hammer and some nails. Make sure your hammer has a comfortable grip and is not too heavy for your hand. You want to be able to swing the hammer with force but not lose control of the weight. There are special hammers available for women and people with a smaller body build.
When you are hanging items, you will want to make sure that they are evenly spaced and not crooked. You don't have to spend a lot of money on fancy measuring tools, but make sure you get a measuring tape that can at least span the length and width of your room. A simple bubble level should do the trick to help you make sure those pictures are up nice and straight.
