I have some extra leather from when I made my Western style gun holster.  I actually have enough for a nice tube style cue case.  U have some basic ideas of what I need to do pattern wise.  I'll just wing it.  But there are some questions on things I might use.  The inside tubes themselves?  I guess I could tip apart my other case and find out.  But that would suck.  Any help and pointers would be appreciated.  I have pretty much all the tools I need for leatherwork.
