I level up in the pines and then take the vine grasses and compound them into shoes and boots and take cypress and make bows or whatever comes out. I compound all sorts of stuff and refill two coin machines two or three times a day. None of it is very high level but none of it can be bought in the stores on the island so all the low level people just love it. I sell tons of stuff. The bows especially are very popular. I've seen others do the same and it hasn't hurt my business so I'm not worried about passing this tip on. :)
