Playtesting

In half an hour I'll will be going to primary school De Dubbeldekker, to show all my visual designs to my 'testpanel'. I hope to find a definitive favorite in the visual designs I made to get a good understanding of what is attractive to both the boys and the girls.
I've printed all the visual designs out (not only these in this post, but also in earlier posts) and I let several groups of children choose which one they like best. I already did this test earlier, where I came to the understanding that my target audience is very fond of patterns, that's why you see so much designs with patterns in them.
