Have you read the blog posts about the workshop? They’re a fun read! Fun fact: my little Miss M was the one being made in the photos.
The blog is a useful resource for information, especially measurements and size comparisons.
Colette reviews the Little Miss M here:
http://fortheloveofmassaccesi.blogspot.sg/?q=Miss+m
“Approximate measurements are: Width: cm. 30 (11.8”), Height: cm. 22,5 (8.8”), Depth: cm. 10 (3.9”) and Strap drop: from cm. 27 to cm. 33 (from 10.6” min. to 13” max). I made no customization requests with this style.”
There is a large version of the Miss M, which I do not have, but you can find pictures of it in the photo gallery.
Colette didn’t review the Midi Divina, unfortunately. I sold mine a while back, so I can’t help there. I hope one of the other ladies can measure theirs for you. I think Hopeless Bag Girl has one?
About leathers, nappa can be stiff too as Marco will reinforce it. It has a luxe texture and isn’t shiny smooth. Croc and Venezia are stiff and textured leathers. I don’t know if Venezia is still being offered.
