I am thinking about using wafer paper to make the sails on a boat.  I don't think 8 1/2 by 12 wafer paper will be big enough.  I have looked but can't find it any bigger.  Maybe it is only a standard size.  Any ideas?  Thanks

I've never seen it bigger. Most sheets are international A4 size, which is about 8' x10.5" or so.

thanks
