Was the pattern photo-copied from an original to be blurry? I purchased a pattern some months ago and I believe the pattern was a re-print. A lot of the patterns are printed on 8 1/2 x 11 copy paper and you just don't know if it is someone profiting off from an original pattern they purchased. I recently ordered Over the River and Through the Woods. It is printed on paper that could be very thin copy paper. White paper folded and printed on both sides. I ordered 2 purse patterns from 2 different companies and designers. Both were very poor quality prints on thin copy paper. I was disappointed with trying to figure them out. I was told by the sender that is how they get them.
Go into a quilt shop and check out their pattern wall. The majority are in clear 'bags' with copy paper patterns. I don't know much about patterns, but it could be to keep the costs down. Contact the person/company you purchased it from and let them know your thoughts. If you have problems figuring out the pattern, I bet you could get a personal response from Sue herself by going on her website.
