I usually look out for party ideas that are unconventional and out of the box. I learned that Youtube is undoubtedly a very good source for these tips. All you need to do is head to Youtube and do a search for "birthday party tips" and you will find hours and hours worth of videos with numerous excellent suggestions. The problem is, who exactly has the time to watch them all? So I am on a regular mission to compile some notes so as to save me and hopefully others some time.
