I'm not familiar with that pattern...are you trying to shrink the design down so each sham would have the entire quilt pattern represented, or are you going to just use a full-size section of it?
YouTube probably has a bazillion videos about how to make various types of pillow shams, if it's just a construction question you have. If the pattern has a table runner pattern, I bet you could adapt that to be the face of the sham pretty easily....
