You can get cheaper sheeting though.![]()
Its easy enough to do it yourself if you are "handy"! You can get 2 or 3mm acrylic cut to size if you dont have the facilities, tack the pieces with CA, tape up the joins, then apply a bead of clear silicone around the inside seams to give it strength. To hide the joins, I use softwood strip to look like framing. If the pieces of acrylic have been laser cut, you can use Tensol or similar which negates the need for the strip.
Like I said, there are places who will cut it to size for you.....Problem is I don’t have a band saw or laser cutter so I’m kind of asking anyone available to help. I think I’m ok with putting it together but straight edge cuts? No chance.
