I have been experimenting with sawdust as a material to sculpt with, looking at mud nests I think that I could replicate this with sawdust. Having said that my initial want to create brick structures out of the material is still very strong though I was nearly put off by peers and tutors. I am wondering if it's because they cannot visualise it the way I can or it may be that they feel I'm planning too much. However I think it will be useful to the piece to do both, to construct the object then break it down to create the nests. I think that this could potentially work very well.
