The most obvious tip is to hire any props instead of buying. Hiring props is a fraction of the cost of buying. This is not only cost effective but environmentally friendly as well, the props you hire get reused over and over again.
If you have decorative items at home that would work with your wedding decor consider using these too, think cushions, rugs, vases and candle holders for example.
Consider using coloured candles, such as these beauties from Ester & Erik, instead of flowers to add colour to your tables. This will not only reduce your florist bill but your candlelight becomes more of a style statement.
Instead of favours, which often get discarded at the dinner table, make your place names so beautiful guests will want to take them away.
We’ve all seen amazing flower and foliage installations but these can be really expensive as they require a lot of flowers and are time consuming for the florist to produce. A great alternative are potted trees and plants. Some florists hire these out or you may have plants at home you can use, they make a big impact at a fraction of the cost and are more sustainable.
If you want to try some DIY for your big day then making your own signs is a great place to start. You can buy calligraphy practice books online or print out practice sheets, once you have mastered it you can then apply this skill to chalkboards or even fabric banners.
Reuse your decor throughout your venue, for example, consider moving your ceremony decor to other parts of the venue after the ceremony. Get the groomsmen to do this!
If you want to have a menu for your guests then have either one per table or write it on a chalkboard somewhere your guests will see.
