In an effort to distract myself...program question

I pretty much have to do programs to explain the multiple parts of my ceremony, so I was going to buy a simple set from AC Moore that had gold flourishes to print myself.

How many programs would you think you need if you're 'shooting for' 125 guests? Our A list is at I believe 167, but of that number I think something disgusting like 78 are OOT, and nearly 20 are children. I'm really not expecting more than 75/80 people at the church, and that's including the BP! Do you think 100 would be too much? Should I estimate 1 program per family unit/couple?

Because of course I can't do anything simple, and I had a BRILLIANT idea for programs today. Nerdy, but brilliant. Going to try to emulate a book cover and will probably contact my invitation vendor to do this, because it's going to require card stock, and lots of ink because I need a sheet of light card stock printed with a black background, etc. My sister would flip her shiz if I even dared ask her to do it for me and use all this ink, otherwise I would love to DIY to save money. Sigh...
