8.5 x 1.
I went to a baby shower tonight and made this cute little (read: huge!) bag to go inside her diaper bag. I envision she'll put diapers and wipes in it, and then hand it and the baby to her husband when the baby needs a diaper change. Or, it can hold an extra outfit. Another fun use would be as a gym bag, for when you go workout and put your child in the daycare for an hour.
It folds up easily and is machine washable, and measures about 12 x 15
I have not yet worked out prices for these. If you're interested, leave a comment with your email address, or email me at email@example.com.
