Ok... so the church doesn't allow bird seed and bubbles never seem to work (must be a problem with me 

 ) so we decided to do ribbon wands.
So my question is this:
we are inviting 200 guests. The mass is at 3:30 on a Friday.  My father keeps telling me not a lot of people will come to the mass bc of the day/time.  How many ribbon wands  would you have made or purchase?
I was thinking maybe 150 but I'm wondering if you think I can get away with 100?
Thoughts?!
