How to read save/read ItemMeta to config

here's what I have:

Code:

 String id = args[1];
              String path = ((Player) sender).getItemInHand().toString();
              String metaPath = ((Player) sender).getItemInHand().getItemMeta().toString();
plugin.getConfig().set("save." + id, path);
                  plugin.getConfig().set("save." + id + ".", metaPath);
                  sender.sendMessage(ChatColor.RED + "[NBTTagger] " + ChatColor.GOLD + "Item saved");
                  return true;

I can set it just fine, but how can I do
item.setItemMeta(config.getmeta)
? thre is no method called config.getItemMeta, altho there is config.getItemStack
