That is so cute!
What are the dimensions?
well, I made a drawing (or an attempt...
) like the front of the bag put into paper:
the bottom rectangle is - 41cm x 16cm - or - 6.25" x 16.1" .
(so the side of the bag is 16cm, meaning the pattern to cut the body like the picture, so you you can sow it, woul be 41cm PLUS
8cm on each side
did I make at least a BIT OF SENSE...?
