They are made from card stock, cereal packet card, foam card and a lolly stick. Also paint as well, mainly cheap acrylics.
With basic colours.
In its raw state, I used the foam card to create two legs them joined them with a lolly stick.
Another lolly stick up the back for more stability and strength, all glued in place with PVA and left for an hour ish to dry.
I think some in purple might look nice too.
