A fun idea for your wedding is to ask for you barman to create a signature cocktail to name after the couple!
Add herbs to your floral décor (mint, basil and rosemary smell wonderful) Alternatively, consider offering miniature herb plants as favors to your guests
If you're not a flowers fan why not consider filling a glass vase with sweets (smarties or m & m's are very effective), slices of fruit in water is also a lovely idea ( mainly oranges or lemons)
Carnations, if your flower budget is limited, why not consider using tight bunches of carnations in a square vase; the effect is very modern and minimal.
A single stem rose in a tapered vase gives a very minimal yet elegant look to the reception table, place one in front of each guests if you can stretch to it!
Fairy lights, these add romance and atmosphere to the chosen venue and can be effective in nearby trees or wrapped around columns.
Hanging lanterns are an inexpensive way to create an aisle, light a pathway, or add interest to a balcony area! They can also be used in clusters as centerpieces on tables.
Children's entertainment, it's a really good idea to organize some entertainment if you are going to have more than a couple of kids attending your wedding as they can become rowdy and ruin the evening. A clown or sitter will usually be sufficient.
