You mean you can't knit a baby blanket or throw together a quilt in a day? heh.
I usually have some leftovers to 'regift' but but you said you didn't...
How about a frame you make intoa baby one? make a 'matt' on the coputer with a line for the babys name, date of birth, and weight, length to be filled in later (search stores online to see what they say, then make it on your favorite print place, I think HP has templates of many sorts free, cause they want you to use more ink) leave a space for a picture or two of course.
or make a 'scrapbook page, again leave space for a picture to be filled in later, if she is the type to scrapbook, give her a binder and several templates....or just the material if she really likes that sort of thing...I don't...Ill take the template any day!
If you have a small scrap of white cloth you can make a tiny diaper out of it...and nowadays cloth doesn't have pins so you can use glue (to simulate velcro) put iseveral on a couple candy bars or hersheys kisses, tell her she will need them shortly after the kid is here! heh, preferably a 'take 5' or kisses...
if you have a chance to go to a store at all, a 'diaper cake' is cutesy, use diapers tied for base layer, then less daipers tied for secon (tie in a circle hmm guess you might need to see one to know what it looks like and how to make it....) well if you have, attatching some dollar store teethers is cute or baby spoons, or clothing/blankets/cute animal...(IMO, and this is totaly NOT PC, avoid the pacifiers and bottles...I never used em and found them annoying to see on a gift......even if you are pretty sure she will use them, you wont go wrong leaving them off....again justIMO)

but I wouldn't buy theirs! and when it says 'cake board' it means cardboard cut int he right size....(least that is the frugal translation.
I have heard you can make cupcakes, but have not seen a picture yet.
My favorite gift for when the baby came was food! I really didn't have energy to cook, and DH only knows so many meals......not sure how you can transfer that to shower gift..maybe GC to a take out place? hopefully bought on discount, or something...
