You can make them but you would have to breed a pinstripe (or something that has pin in it). So if you breed a pin to a normal then part of the clutch would be pins and part of it would be normals. Because the Pinstripe is a domanate gene there are no breeding of hets involved. Here is a link to the NERD site about the pinstripes. http://www.newenglandreptile.com/ner...ll-python.html
