Using an origami dress (you can see the tutorial here) and 3d quilling hat all is made from 4 mm strips of paper. It has taking me a bit too long to make this hat because as you can see the edge of the hat it is made from really small quilling that gives the hat style. My idea to alternate between apple-green and bottle-green was not bad at all but in practice is a bit different when you mistaken the colors. At the end i believe that i've done a pretty decent job.
For this card i've used an manequin shape, decorated with an abstract motif and a hat. The hat is made from 6mm width paper strips.
