Hello lovely people of mumsnet, I was hoping you could offer some advice on a little seasonal romantic gesture I’m planning for my girlfriend. I realise this is mumsnet and possibly not be the normal forum for a request like this so apologise to anyone who thinks I’m out of order for posting here but hopefully there will be a few folks on here who don’t mind sharing some ideas with me. 
So briefly my plan is to modify an advent calendar for her so it contains a surprise romantic note behind each window to make her smile for each day of December. After w lot of experimenting I have found a advent calendar at the supermarket which I can cunningly dissemble and reassemble so the notes will be a surprise for her when she opens each window.
Where I would really appreciate some advice is on what sort of things to put on the notes. I realise this is personal and will have to come from me but your ideas will hopefully give me inspiration.
So ladies, if you were in her shoes what notes might make you smile and feel appreciated?
Thanks again for reading and any advice offered. My girlfriend is a very hard working mum and I really want to make her feel deservedly loved and appreciated particularly at this time of year.
