This pattern is quite complicated. It was based originally on text from holy writ, with the seven headed dragon with diadems (those would be the bands around their heads) and horns, i think I remember 10 horns on 7 heads (so some had two horns), and tails flashing in the starry sky to bring down the stars from the heavens. This is appropriate perhaps as a round format for the year of the dragon (which doesn't have 7 heads however (LOL) but is based on the black dragon, a real animal) but someone might like it to commemorate the year of the dragon 2012.
This pattern has enough tiny pieces that a letter size pattern would be pretty useless, this therefore is supplied only as small as 42 inches round (the pdf file is that big, and would need to be printed by a quick print store.
