I laminated mine. You can buy a laminator and sheets to go with it for less than $40-$50. $20-$30 for the laminator and a pack of sheets is $5-$10. If you go that route then you have it for future stuff. I've used mine a lot to laminate flimsy player sheets or game aids.
I've considered this, but I've heard the odd horror story of someone who got their sheets laminated and somehow ruined them. For someone who's never laminated anything, any advice on what to do/not do?
