I would have been nice if they gave you some idea on what she likes - gardening, sewing, quilting, etc.
I've seen some great pics with those ideas that would be great for 80 year old. Does she have a sense of humor??? There is one on CC that makes a play on the Serenity prayer - really cute.
Not much help - good luck.
I'm doing an 80th bday cake for my aunt. I love Thanh Thanh's cakes, so I am going to "try" to incorporate one of hers in my design. I just love the pink floral one on the first page second row of her album. I would think anything floral would be great for an 80th.
