AMy graduation is this month and after that I will be schoolfree for 4 months. During these four months the wedding season will take place. Now I was wondering how I can get more wedding cake orders. Does anyone has some advice?

You could try connecting with other vendors in the industry: photographers, florists, etc... They could recommend your cakes to their clients if asked and vice versa. You could also try to get into a bridal show, but those can be pricy and often the vendor tables are booked months (even a year) in advance.
