Toad is going as Batman (posterboard mask, an extra cape). The Doctor is going as Doctor House (a paper cane, twisted with glue to keep its shape).
Van Gogh is going as that redheaded doctor in Grey's Anatomy. Look at the resemblance, it's eerie.
Oscar Wilde is what only Oscar Wilde can be: a bird with ridiculous plumage. This is all out of paper and gloss, attached with plain clear tape, turned inside out and hidden. And I made Poe a pair of Groucho glasses with pipecleaners, wire, and paper. Poor Poe.
The candied and caramel apples are made of paper and aluminum foil on toothpicks, painted thickly with watercolors for the deep color and shine.
The lollipops are foil and tissue paper on wire; the other candy is foil and tissue paper.
The Halloween baskets are part of this ridiculous drinking straw that they sell at the dollar store. I scored cut lines with a scissor, and because the plastic is hard I didn't want to risk cutting through and ruining a scissor. I used a wirecutter for that, and it worked fine, half of the time. The other half, I ruined the pumpkin. Thankfully, each straw has four, and it comes in a package of several. Then I covered it with orange tissue paper to give it a nicer texture and a less plasticky shine, and added a wire handle.
The 'organic zombie' growing out of a flowerpot! Okay, I've seen this somewhere before, but I don't remember where. Basically, I used one of my mess-up hands from the dolls I'm trying to make, painted over the skin tone with green watercolor, blotted when needed to create that gross, mottled look, and made a 'seed packet' out of posterboard and part of a skewer.
Annnd here's my Halloween costume. Bowties are cool. Trust me, I'm the Doctor.
