Hot Glue Guns: I make new costumes every year for my family, and some years I run out of time. HOT GLUE GUN. Skip the sewing machine, if you're careful, you can whip up almost any costume in a quarter of the time. I've put together Miss Piggy, 2 princesses, 2 gypsies, a (pregnant) elf, an indian princess, 2 unicorns, a saloon girl, and 2 vampiress' in the last 8 years with a combination of sewing machine and that little Craftsman glue gun.
SCARS and Bullet Holes: I got some flour and water and made a paste that I smeared in places on my face. Then I used some of my wife's makeup to make it flesh colored. Then I took a pinhead and carved out holes in the paste, colored in the holes with black eye liner and had instant bullet holes ! I added some fake blood dripping out too. It really looked good ! Yopu can also make scars this way !!!
BLOOD One pint of KARO Syrup (the clear kind) ounce RED food coloring one or two teaspoons of yellow food coloring. mix the KARO and red first then add the yellow a little at a time, till you get a warm yellow color. dilute with water if you want. This mix can be put in the mouth or even swallowed, don't get in your eyes, red dyes can cause eye infections.
SCARS One teaspoon or one packet of KNOX gelatin One tablespoon of hot water (not boiling you don't want to burn your self, as hot as you can stand) one 35mm filmcan to mix in a plastic knife from taco bell to mix with or a popscicle stick mix the gelatin and water in the filmcan, when mixed it looks like honey or snot spread it on your skin to form scars, burns or whatever after the gel has cooled (at his point you can gross out your friends by eating the gel it has no taste but looks gross) don't eat it after you apply makeup color with theatrical makeup, or cheap lipsticks brush on babypowder with a cotton ball, to set the colors have fun but be safe, use common sense
I credit Dick Smith for these ideas, from his book "DO IT YOURSELF MONSTER MAKEUP HANDBOOK" all the materials above can be obtained from your local supermarket, for other ideas visit your local magic or costume shop.
Go to your local costume store and ask for *Spirit Gum *Nose Wax (Putty) *Liquid Latex -Apply spirit gum to spot where you want a scar, cut, lump, etc. -Shape wax to fit your purpose and press into spirit gum (allow spirit gum get tacky {sticky} first). You can make an incision in the wax for cuts. -Brush latex over the scar and allow to dry. -Cover scar with base make-up to blend with skin. -Apply blood* to cuts and colour to bruises and scars. (* For blood, mix white corn syrup with red food colouring (green if you are a Vulcan) and apply with a Q-tip.)
