Here is the final product...
The only good thing that came from this whole project (besides the fact that it will be easier to convince my hubby to get us a nice new couch soon) is that I learned how NOT to do it next time...and a few tips on how to do it if you want to:
1) If you don't have a really smooth surface to work with, get a good leather filler. Unfortunately none exist here in L-town, but I did find some good ones online...and I would definitely try them out next time...it would really smooth out the surface.
2)I would use a primer. The lady on the blog that I read didn't, and it might be tricky to find Vinyl Spray Paint primer...but if there is one, use it.
3)After that I'd use a LOT more spray paint than she did, we went through 6 or 7 cans, and could have easily used more.
4)ONLY use Vinyl Spray Paint...I cheated and did half and half because it's pricey up here in Canada, and hard to find. Next time I go to the U.S. I plan on stocking up on every kind of random and cool cheap spray-paint I can.
