Honestly, I hardly ever use papier mache.....I would like to...it is
inexpensive, easy...etc...but way to messy!!! If you have never done a papier mache
project with students...I would keep it small..and more like a bas relief (mask
on a form or something like that). That way the students only have to lay
the pieces flat and get lots of layers on. There are many on this list who use
papier mache extensively, I am sure you will get lots of great advice from
them! I am always very cautious and controlling when using a media like that.
As for time...I would have one class period for building the armature or
form. Then...I would invite parents in to help the class period you apply the
papier mache. Then I would have 2 class periods for painting. (use acrylic not
tempera on papier mache....) Then 1-2 class periods for adding design details
(if you are going to use things like trims, fabrics, etc.) You are pretty
much looking at a 6 class period project with papier mache. Just make sure you
break it down! The kids love it...but you have to be "uber" organized!
