The paper piecing books with the CDs will give you percentages to blow up what you print off your computer to give you the size you need. Kinkos Staples and places like that can print on 11 x 18 paper, if needed, so you could take one quarter of the pattern and get it increased to size then just copy off the 4 copies you need, plus maybe a couple if there is a need to redo (polite way to say, if you mess one up!).
