I like this topic, but then I like hats. Between us my mum and I have over 20.
I tried a new technique with this one. I cut the shapes of her hair and face out of foam, printed them with acrylic paint and drew the details on in pen. I then cut up a Boden catalogue for all the collagy bits. (You buy one swimsuit and they send you an average of 3 catalogues a month. It's ridiculous)
