Whichever way you decide to go with your flowers, a lovely idea is to try and tie your whole theme together so if you're going for roses, then have a rose design featured somewhere within your headdress. Look out for a company who can work with you and your designs and most importantly your budget to create that one_off, bespoke creation just for you.
You can also make a huge wonderful bouquet for the dining table. Add candles around it or even inside it to give a stunning look. Small flowers can also be used to make outside decorations on a candle, even dried flowers look so beautiful and soothing to the eyes. You just have to dry some flowers, glue them on a transparent sheet and then wrap the sheet around candles. Flowers can also make wonderful Christmas gifts. Another idea is to use flower decorations on the place around the tree and a few paces in front of it.
