If we want to make coverings and decals with poly-carb or such materials, does this apply to the 12"x 24" limit? I hear different views because it is non-functional decoration.
Thanks!
As per this Q+A from last season, there are no restrictions on polycarbonate used for non - functional decorations. I have not seen anything more recent contradicting this.
Cheers,

Thanks! Beautiful Decals here we come! 
You’re welcome! Be creative!
Just keep in mind what could be considered functional… if it is being used as protection (and actively as such), that could be considered functional.
Laminating paper works well and can’t really be argued as functional if you’re truly using it for decals.
Hope this helps!
