WOW I see~ I didn't know this world of art yet ! I bought my own starter kit of watercolour and it's a 12 colours and they are in their own cuvettes and no space to add more colours...
But this is amazing, @veta-less ! I am excited to see what you would make in the future :D
О, @veryspider I didn't know either, until I started choosing watercolors! :)) For me it was still a discovery that the roof of the box is a palette!
