Hi there...............
I would make sure it's a font well liked by the other Cub Scouts...... and to be 'Politically Correct', Girl Scouts and any other groups looking to play with Cub Scouts. To make sure it's real, look it up on Google and just drop it into your font folder. If it goes in Okay, you're fine to proceed. It'll be real alright. For 50 lines, cut on your animal cutter, you might consider some of the more decorative styles as they have real pizazz and regardless of the how tedious it is or not..... go with what you like on the screen. At 1/8" high, consider going upper and lower case, so it's easier to read that much copy. Before putting it on the plywood, you might want to consider painting it. Cub Scouts are in blue, so I'd imagine a blue background with gold letters will do real nice for them.
Remember, when it's finished, you must collect all your money, cause I'm sure being non-profit they won't give you a deposit, which is quite alright, since they're honest little kids.
Good luck and if you don't mind..... a friend of mine lives in Florida near you and his son turns 10 today. Make sure you tell him happy Birthday for me.
