I did the Vambraces (or arm plates) of the Assassin’s Creed 1 costume.
Here how I proceeded :
You will need for the vambraces :
– Foam sheets – Pen – Scissors – Silver pen wide tip – Silver pen narrow tip – Hole puncher
After printing the vambraces design (found them on deviant art) I cut each of the 5 leaving about 3mm – 1/8″ around them. Then I retraced around all of the 5 with a pen on a black foam sheets (dollar store). I cut all of them on the line with scissors.
With the printing on the side I retraced de design on each foam shape with the silver pen, making the details with the fine tip pencil.
I punched the holes with the hole puncher.
I managed to cut and sew a belt out of vinyl for my friend and we applied decorative nails with the industrial puncher.
Now I’m waiting for a photo from our assassin’s creed enthusiast!
The rest of the costume has been done with the very complete tutorial from this website : http://www.assassinscostume.com/altair/under_tunic/
