Thanks to everyone for their reply.
This is the pattern that I wanted to try out.

I see that the full page pattern is the reverse of the finished product which tells me it's OK to use that pattern. I am taking Lassenkid's comment and running with it. So got an enlarged copy where they make house plans copies and will try something bigger to begin with, then I can try the tedious stuff.
