Whenever you are on a project, try not to throw out anything until the project is successfully completed.
Not only should you inventory all parts when opening a new item, whether it is an Ikea dresser or a ceiling fan, it is a good idea to keep everything until the project at hand is done!
Sometimes you get in the middle of a job and find something doesn’t fit or isn’t working. You may need to put the old item back together until you resolve the problem with the new one. Or you might need the original packaging to return or request a replacement something that didn’t fit like if should have. There are many examples I could give as to why, trust that I have learned this bit of advice the hard way. Keep everything until you have successfully completed your project!!
