Nancy is my hero!! When we first became friends I was so intimidated by her talent, but one thing I learned VERY quickly was that her personality is just as beautiful as her cookies, if not moreso. She is so giving and kind!
Oh, don't get me started on Kneadacookie either!! *WHACK!!* That's me smacking her with a spatula to try and splatter some of her talent on myself!!
(not to say the other's you mentioned aren't fantastic, I am just not *YET* familiar with their work. You can be sure I'll be looking 'em up!!)
My biggest problem with cookies is that the recipe that I think tastes good for the cookie itself spreads horribly, the non-spreading ones don't taste that good, and as for icing... royal makes me hurl. I like 'em with buttercream, but that leaves you with a product that is totally unpackagable. But man, does it taste good!
