One of my favorite designs is the flying pig.
I commonly build them in 2 sizes - small 10in pigs and large 18in pigs.
I typically leave them unpainted, though I may add some paint highlights here and there. They can be built standing, sitting, or set with a loop for hanging. I can build them in just about any pose you could ask for.
I always put a collar on my pigs with a charm hanging off them. Typically a bell, but other options are available.
