First: Thanks for all comments, it's overwhelming and sooo nice :-)
These drawings were send; 9 and 14 mars. I did a preview earlier and like to present them here now. Some ongoing drawings are: lighter for La (Think is ready now), milk for Ca (calcium) (I hope this is valid?), water-glass/lemonade-glass for Si and Coins for Ni and Cu. I'll be back with previews for these.
