I regularly want party approaches that are unique and out of the box. I found that Youtube is normally a great resource of this sort of ideas. All you have to do is browse Youtube and perform a search for "birthday party tips" and you can see several hours worth of online videos with countless very good advices. The trouble is, who exactly has the time to view them all? Thus I am on a continuous quest to gather some notes so as to save me and hopefully other people some time.
