It is possible to enlarge a PP pattern. I have one enlarged 263% (making a bed quilt from a wallhanging pattern).

I have taken p.piecing to the college and they enlarged the pieces for me. Worked okay. Good luck!

that page or in the directions it should say make 40 copies or how ever many you need.

Thanks to everyone for their reply.
This is the pattern that I wanted to try out. http://www.silverliningsoriginals.com/qc/pilpuppy.html
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.
