Apparently, this is one of the exercises you're supposed to do when learning #watercolour
My current (and first and only :D ) set: a student-grade pre-assembled one that a) suits me just fine, since I'm still at the stage of “first attempts” b) costed about 1 eur less than a similar empty box from the same store, and appears to be practical and of good quality.
(The pink looking thing in the upper right corner is copper, and while it's technically watercolour I've bought it for calligraphy.)
