17 days wow!!! you sound so calm!!! i think it's good that you're starting your thank you notes so soon...with so many to write out, it's obviously going to take awhile!!! why don't you try to do at least 10/day, that way, you'll probably do more than that and you'll finish before the wedding even gets here!!! that's my 5% rule by the way...i use it for everything, especially cleaning, and i always do more than 5% so i always get my stuff done fast!!!
