Wedding Ideas!!??...DIY...?

I don't know what your idea of low budget is but 100 guests is not a small wedding. that's how many I had last year and it was a big deal to plan. open bar will run you about $30 per person, plus gratuity for the bartender FYI. that's what our venue estimated, people drink about $30 worth if it's open bar. our catering was over $50 per person, you do the math. and the venue rental fee was 4 figures on top of all that.
