This might be a stupid question so please bear with me; how do you guys go about asking for a custom or semi-custom pipe. Is there specifc makers that offer this as a service or will most established artisans oblige? Furthermore, there's a couple specific shapes out there that either aren't easy to find or that I would very much like a variation of. It that a generally accepted practice/request or is it like asking an accomplished singer songwriter to play Freebird over and over again?
