I made these figures from blank Munnies in 2008-2009. I don't remember where I first came across these DIY figures, but I'm glad I did. They had gotten me to try all sorts of things I hadn't tried before: sculpting, sewing, jewelry making, just all in miniature.
I would start with the blank figure and most often add extra features using polymer clay. Then I would paint the figure with acrylic paint and hand-sew any clothing if needed using a variety of materials like leather or fabric. Most accessories were made with clay or wood, but in one case I used a mini bottle of Tabasco sauce.
