Now that you've decided on a theme, the next step is to set a budget. Throwing a shower is lots of fun until you start to total all the receipts. Then you find out that the extra $5 there and the extra ten cents each here somehow added up to more than you wanted to spend. And then you'll feel bad because you put yourself in an uncomfortable financial position by spending more than you had allotted in your personal budget. You might find yourself begrudging all the work you did and money you spent.
