This achievement requires you to craft 20 different items in a single game.
The best way to do this achievement is by making smoke bombs: 1 smoke bomb wants 1 fuel and 1 fuel wants 2 berries. So:
2 Berries = 1 Fuel = 1 Smoke Bomb
So make a sickle, gather berries, make fuel, make smoke bombs and repeat until you get the achievement.
