See this?

Yes it is crocheted, but that's not the point. I'm stumped by this thing, not because it took me three tries to figure out how to make a single crochet, or by it's shape (it's a hyperbolic plane). But because this pattern (from Interweave Crochet 2005) called for 200 grams of yarn, and this little baby only used about 20 grams. Typo? I don't know, there are no corrections on the web site. Did I make a mistake? Don't think so, I followed the instructions exactly and even "got gauge." That in itself is a minor miracle for me in the crochet department. If anyone has any insights please help me out.
Aside from the confusion this was so much fun. I'm not a crocheter, this is actually the first crocheted thing I've ever finished, but once I got the single crochet thing sorted out it was so easy. I'm already planning another one, a big one that will sit on my coffee table and just look neat. Another great thing about it is that you have to use cheap old worsted weight acrylic to get the stiffness it needs to keep it's shape and that is totally in my budget right now.
