I have been sending my son and his wife pieces of miniature furniture that I make, so I have designed/ designing a sort of beachhouse or shack to put their furniture into. It will be open fronted and clad with (Australian)wriggle 'iron'( corregated 'iron')
I have been wrestling with the use of MDF because of the fragileness waterwise and because of the toxic glue used to make it and also it contains silicon which blunts tools.
I know that it is made from timber as is plywood, but plywood is closer to natural or solid timber.
As plywood is cross layered, it is strong.
As someone said "That what I like about nature, it's so natural"
