I only know of medicine bags. Could not tell you even that off the top of my head. I have tried for years to enchant a gold plated Marine Corps ring with little to no success. If you figure one out, let me know.
Believe you will enchant/consecrate/etc..before you do , say some commands of what you want the item to have /do/contain and end it with some other words of finalization ...do it and retry over ,no special undoing needed/again. :-)
