I had used this technique in the past to make a pattern for a shape and easily, while making fitted clothing and fabric patterns. I wondered if this could be used with my clay model and if it could be translated into large scale. I planned to cover the model with tape , remove it, then with strategical cuts flatten the shape, draw round it to make a pattern. Once the pattern was made I planned to scan it into the printer to scale it up so i could cut the pattern out in foam sheets to create the same shape but larger.
Here i’ve started taping my model.
Finished duct tape cast.

I Attempted to flatten the more curved half with cuts but it turned out the shape was too small and fiddly for me to cut it flat. After an hour or so of no progress I decided this method would not work due to its small intricate shapes.
I needed to decided a different method of constructing my mask. I looked at the sound structural integrity of the duct tape cast and figured why don’t I just make the mask from paper mache. I feel confident in this technique and felt it would better allow me to create a more polished final product.
After deliberation I decided the best method to make the form would be to use chicken wire to mould a simple skeleton. As the head is to be worn it would not be a good idea to leave the chicken wire in the structure as its hazardous. So I wanted a way to remove the chcicken wire after so figured a cling film barrier to paper mache on top of would allow this. To be sure I did a small simplified test piece.
The cling film worked well and it came away easily. I used wood glue for this but felt it could be a little stronger so I must reenforce the paper with a stronger material maybe?
