Well, I just just plain computer paper most of the time. I scan it at a super high resolution though, like 16,000 by 26,000 pixels to get it to look decent. Then I open it up in GIMP and resize to 1000 pixels at the longest side. Takes a while, but gets a good result.
This picture makes no sense, and I will tell you why.
Pichu and Electrobuzz can not control electricity coming off of their body. If it is the same type of electricity, it is not a problem, but Pichu uses static, while Electrobuzz uses current. Obviously a problem. So, unless your abomination of a Pichu planned on getting its ass fried by 10,000 volts of pure power this is a terribly misinformed picture.
