Easy ways to make money for kids

Fish raw lobsters and bank them, they will fetch a good price at the Grand exchange for 400gp each(Its a LONG way from karamja to the nearest bank though) or sell them at the nearby general store.

The BEST way in my opinion, and that I wold recommend, is to mine clay, southwest of Varrok. Buy a few buckets and fill them up with water at the varrok fountain and bank them, you could mine a full inventory of clay in about a minute, take 45 seconds to wet them with the buckets of water, then take another 15 seconds to bank them/sell them. They sell VERY quick and are about 200-400 gp each depending on the econonomy. Sometimes even higher! Also, you only need 10-15 mining, dont remember, to mine clay, so you wont need any pro skill level to get it.

Another way of making money is mining pure/rune essences, dont remember if pure is f2p or not. You can find an Essence mine south of Varrok’s East bank(the small bank). talk to the rune selller with the skillcape on in a little house and ask him to teleport you to the rune essence mine(be aware though that you have to of done Rune mysteries quest for him to teleport you there.) You will have to walk around to find the big chunk of rune essence(CANT MISS IT, ITS HUGE!)you need a low level to mind the essence, like 15 or so. and the essences sell for 100-300 gp each, i think. When you are done mining a full inventory of essence, which will take you about 30 seconds, look for the purple portal next to the giant chunk of stone and it will telport you out.

Another one of my favorite ways to make money, which not many people know of, Is to kill black unicorns in the wild. I dont exactly remember where they are located in the wild, but i think they are near the stealing creation minigame. The Unicorns are level 21 or so, easy to kill with your combat skills, and drop unicorns horns, which sell for an amazing 1,000 gp! they’re are a BUNCH of unicorns so it will be quick to fill up an inventory with horns. Just bring a few Tuna to heal yourself and your good to go! Be aware though, that revenants lurk in the wilderness, and as a f2p character, could kill you easily, so fill up your inventory as fast as u can with the horns and get out of there! (bring some teleport runes with you so you can teleport yourself out if you are about to die, a revenenat comes and you think you cant handle it, or you have filled up your inventory with horns.)
