Brat - I didn't want the huge labels either. I don't want a big chunk of my quilt covered up with my info! So I stuck with 2.75" by 5/8". They have my basic info, and a paw print for my 'logo'. They will go on anything I make, whether it's to sell or as a gift.
As a side note - Do you guys wrap your quilts when you gift them? I didn't... I just folded my baby quilts pretty, put some matching ribbon on the (like you would a present) and called it good. The babies are too young to unwrap, and the blankets themselves look so pretty all folded up like that!
