One of my friends went to wall mart and bought all the stuff that we would need, what ended up being around $6 dollars per person, a lot less than we would pay going out. You can also find pre-stretched canvas online for a cheap price.
We went online, picked a picture that we liked and that was it. We had so much fun, we laugh a lot and, I really think that it turned out pretty good. I even kept my paint. Maybe I will hang it somewhere one day! : )
