Add a NPC of a preist in all the major cities and you could give the pre-crafted items to them and they create the bandages and return the finish product to you, preferable free of charge or for a very very low cost at low lvl and slightly higher for the higher lvl bandages. Example you give the priest in NM the 2x small snake skins + 2 gold, he gives you a small bandage in return. You give a 2x sand viper skin + 25 gold to the preist in silversail and he gives you a large bandage in return. Could also have roaming npcs in places like the dessy, dungeon, on the way to time knight and all other remote suitable areas that could craft as well, kinda like the guide on the way to the time knight. Perhaps have it so if you type /hello trade traveler he stays put for like 30 seconds and you could have him craft them for you for a little higher cost then in town. this would make it more practical to go to some of the tougher areas in the game
Make the Bandages Stackable with a limit of being able to carry 1 stack in your inventory at a time, so you could carry say 5 healing potions and a stack of 20 healing bandages and as you train you still have room in your inventory to collect items for trade in. may also want to consider making the craftable items like the small snake skins stackable as well. would need a stack limit though of like 10 or 20 for items and bandages.
The Bandages should make you recover hp slowly, for the lower lvl ones for example 1 hp per second for a total of 20 seconds = 20hp. Were the higher lvl ones could be 10 hp per second for 20 seconds = 200hp ect. I think one of two things should be added as well either if you take any damage the healing over time gets interrupted or add a time limit to the use of the bandages. Example 1 while using your bandage a small snake hits you for 5 damage and interrupts your first aid so you only end up getting 1 hp per second for 5 seconds for a total of 5 hp, or have a time limit that you can only use a bandage once every 2 minutes. This would still make healing potions a must and prevent people from using them as a heal over time while fighting.
The current system is gonna make it near impossible to train alone at high lvl
, even with the ole hit and run tactic. The high lvl monsters will rip anything up thats not self healing in seconds, and who wants to run all the way to the "good training spots" and hit and run a monster till you use up your 12 healing potions and die, and drop all your gold and lose a big percentage of the exp you gained 
At least with this addition you can carry 11 instant healing potions and a stack of 20 bandages to allow for alot longer training adventures. Would also help the lonley clerics/paladins with healing after a battle with proceeding to the next square instead of sitting waiting for stam to heal all party members, and make the harder/ better exp pod areas in game way more open to be used!! 
I know the post is long, take the time to read it I think its a decent idea. Feel free to add to the idea but be sure to show your support so we can get it added!!!!
