Things don’t always go to plan and everything doesn’t have to be done professionally. It’s nice to be able to just hire someone to do something for you so you don’t have to worry about it, but sometimes, they’re a no show (like the HMUA just didn’t show up at this wedding) and the groom opted to make their wedding cake, because he could and it saved them money.
All this to say, don’t sweat the small stuff. Just enjoy yourself and your day!
