Own flower arrangements

Hey
Has anyone done their own flower arrangements for wedding reception? I’m really in two minds as I would actually love to do it I’m quite a creative person and the thought of spending a few evenings making all the decor actually excites me 😅 however- when it comes to the wedding day itself am I actually going to want to be setting up the room myself when I need to be getting ready. I don’t even want to have my bridesmaids setting up as I want them getting ready with me. Part of me thinks it won’t take long I’ll bring everything assembled but realistically is it worth the money paying someone to do it for you to ensure no stress the wedding morning?! I think so!
I’ve been quoted minimum £1000 for flowers and that is why I’m toying with the idea!! Has anyone else set up the morning of? My venue won’t be able to tell me until 1 weeks before if I can go there the night before to set up so 1 week doesn’t leave me enough time to decide on this so I need to just decide Also for background I’m getting ready at the venue, travelling to a church 30 mins away and then us and everyone else comes back to the venue , so no one else like friends/family will be at the venue that morning to even help as an idea. Thanks for anyone’s advice on this! I almost don’t mind the expense of flowers for the wedding but when I know I can actually do it myself (just the setting up I don’t think I can) it’s annoying!Thanks xx
