A suggestion....for my mother-in-law’s 80th birthday, we gave her 80 small presents (that one can buy at a local dollar store). Wrapped all the presents and it looked like a lot! :-) People always like to open presents...now....a 100 presents (at a dollar each) might seem to be a lot, but if several people got several (dollar) presents (about 10 per person if 10 people attended) it would be very doable....FReegards, FRiend.....
Clever. And the first present would be a small pair of scissors!
