I made the bouquets for both mine and my uncles wedding and have just been asked to do a friends wedding as well.

The best tip I can give you is scour the $2 shops and other places like that, spotlight is also good.

I was able to make mine and my bridesmaids bouquets (3 in total) for around $100 and my uncles cost them around $80 for the bride and her 3 bridesmaids.

Feel free to PM me if you think I might be able to help in anyway, I'm on Tapatalk at the moment so can't see where you're from. I also have photos if you would like to see my work.
