Wow, that's really cool that your first ball python is a pinstripe! Congrats and good luck with her!

If you breed a Pin to a Pewter you could get:
Normals
Pewters
Cinnamons
Pastels
Pinstripes
PewterPins (which I don't think I've ever seen a pic of )
Pinstripe Pastels (aka Lemon Blast)
Pinstripe Cinnamons
