One of my favorite 5th gen bug pokemon: Scolipede Took this guy to the elite 4 Lucky he could stand on his own so taking the picture was easy. Scolipede is completely made out of pipe cleaners and is going to be sold in Fanime '13 artist alley.
For the patterns, I make the frame of scolipede's segments first. Before I fill it in with the magenta(or burgundy) pipe cleaners I put in the oval pattern first and then fill in the rest of the segment around the pattern. That way, it doesn't look like the pattern or decal is popping out and it's part of the figure. I use this technique for a lot of my figures.
