What to do if fiance and i are paying for the wedding ourselves but he isnt to good with his fianances (he'll overspend and not realize) but we're set to spend about $10000 for everything how can we save for our special day?

I would like to know if there are other couples who budget may be 10,000 or under. If you are could you please share some tips, like how you saved, decorations DIYs, anything. My fiance and I are trying to stay in budget because we have to, so share...
