Thank you note woes!!!?

I am horrible at writing thank you notes, I have always been this way and end up procrastinating doing it for so long that sometimes I never do it!! I know this is terrible as I am so thankful for everything I am given. My mother is throwing me a baby shower in two weeks, I was thinking of writing a pre-party thank you note to everyone attending and giving it to them the day of the party. I thought I could write a personal note to each person thanking them for being a part of mine and my husbands life and how great it will be for our son to grow up knowing them etc... and attaching the note to a bulb of some sort (gardenia, tulip, etc..) and saying something like, here is a little something you can plant and always remember the love I have for you (that sounds cheesy, but I would write something similar) What do you think?
