Royal dragon leather is used to train Crafting, and it is always in high demand. Because Royal dragonhide must be tanned into leather before it can be crafted, tanning the hides in bulk can be highly profitable.
While regular tanning can be quite profitable on its own, using the lunar spell Make Leather (which tans five hides at once) can increase the profit by more than 50% while also giving decent Magic experience. The downside is that Make Leather must be unlocked from Livid Farm, which requires 250,000 produce points.
Because the price difference between hides and leather can be fairly small, it is important to buy the hides for a low price and sell the leather for a high price; you can lose out on much of the profit or even turn a loss if you are not patient. Test the profit by buying one Royal dragonhide and one Royal dragon leather. If the difference between the two is less than 200, it may be worth it to switch to a different hide type. In some cases the profit can be more than 500 coins -- the guide prices on the Grand Exchange are not always indicative of the current trading price.
Begin by equipping your staff of fire and withdrawing body runes and astral runes, along with 26 royal dragonhides. Click the Make Leather spell (either in the spellbook or directly on your action bar) and use it on one of the hides. Bank your royal dragon leather and repeat. With fast banking, one can make a total of 26,000 leathers an hour. A Large rune pouch can be used to further increase hides per hour.
When finished, sell the leather on the Grand Exchange. Since the margin can be rather high, consider buying one royal dragon leather first and selling yours for one coin below that. This can save you more than 100 coins per item.
