Made all from toilet paper, corn syrup and red food coloring, various eye shadows and foundation. and watered down glue. It's easy to do, cool for pictures.. But I don't recommend doing it if you plan on wearing it for a costume. It doesn't last long.
Hm, you could. I bet I could make a better version now that I have the actual things and actually know what I'm doing. I did this like a year ago. Haha.
It still looked really good seriously. I mean.. That would make some really good photo's,lots of fake blood, (but browsing your gallery, you use it nicely too!) a dark ally, and a great laugh with passers by.
