I like to give a few challenge categories so more people can participate...the craft has to be in one of the categories each month (and I am pretty lenient!)...so if you make something blue, it is one entry; if you make an organizer, it is another entry. I throw all the entries into a "pot" and then let the random organizer pick a number. You have a chance of winning whether you make one of 20 projects, but obviously, your odds are better with more projects!
Thanks! This definitely answered my question
