Here is the diaper bag that I made for my sister's co-worker. I hope that it is something that will be liked and well-used. After quite a bit of trial and error, I am happy with how it turned out. It is on the larger side, rather than smaller.
The measurements are: bottom is 15" x 7 1/2"
top is 14 1/2" x 6 1/2"
and it is 11 3/4 inches tall
the handle strap measures 33", with out length for the clasping/ connecting pieces
