For something fairly simple, the pattern instructions were unclear and required a lot of thought to figure out what the instructions really "meant". I checked, it was written in 1998. You would think that sometime in the past 11 years someone with no prior knowledge would have tried the pattern and discovered the problem. Ah well, it was good for a puzzle and I like the way it turned out.
I'll send this out with him tomorrow morning to deliver - hope she likes it!
Take care all,
