I want to suggest balloons can be a nice variation on the giving of flowers. Last night I was watching a romantic movie with my mate. The guy gave his lady a balloon and it was not the right thing to do so his mates said.
But I disagree I love balloons. There are places that do lovely bouquets of balloons and you can often put a small gift inside. We have a local craft store that does that but they also sell lots of really nice balloons. The metallic kind and the rubber kind. You can also buy the helium canisters if you want the floaty kind. You can just blow them up and put them on a stick. This works well for a bouquet and is cheaper than the helium option.
It is a wonderful way to present a small gift as well. My Husband actually proposed to me with a balloon bouquet, and a balloon inside a balloon actually had the engagement ring. It was very romantic and a lot of fun at the same time.
Another idea is to write your own message on the balloon with a felt tip pen. You can also get the balloons they tie into animals and make nice flowers with these. My hubby learnt how to make them when he was doing childrens’ parties.
