Cookie messages are much better than bottle messages for one main reason: You can eat them! Yum.
If I were a big cookie maker, I'd definitely be purchasing these from Williams-Sonoma myself, but as it stands, I rarely make cookies and when I do, they're not going to be flat sugar cookies or ones that can even be decorated really. Bring on the double chunky chocolate fudge cookies for me instead.
Wouldn't these make an amazing gift for a cookie maker, though? Or buy them for yourself and gift your baked goods. Just be sure you put me on your list of people to send them to. ;)
