I’ve tried both, personally i prefer the way B looks. However, B is harder to put together and you have to be very careful with it so it does not break, and you might need to use scissors (or something else that can cut the soft plastic) so the pieces fit into one another properly :).
Version B requires much less glue.
Do not iron the beads in version A too much, or else it might turn out squished like it did for me, haha!
Also, I made a slightly bigger hat for B, but feel free to expand the hat in version A as well :).
I recommend using different shades of white for the hat and the eyes + mouth.
Extras are not necessary!
