catmcclure, thank you, thank you, thank you so much.
Part of my problem has been that I can only look at the diagram in the upper left corner on the PDF page ONLINE, since that PDF (and the TIFF) won't print properly from my printer. The pattern pieces come out "OK", needing some line gaps filled in, but the diagram at the top doesn't print out at all. Having to look at it online, without being able to draw triangles, etc. around the pieces to figure out it's construction, has been very difficult. Will have to get to my SIL's to print it out.
As for it being an advanced block...to me there is no advanced, just more time consuming, and more attention needed to detail.
