I have the a similar problem with a well known paper piecing designer's patterns, but in reverse. She gives yardage amounts for each fabric, but identifies them as "medium background 1" and "medium background 2". I have no idea from looking at the pattern how to match these up with actual parts of the design. I wind up spending a lot of time matching up pattern pieces to the pattern, going to the pattern to find out what fabrics I'm supposed to use with those pieces, and developing my own diagram of where "medium background 1" belongs in the design. To make it worse, she will then mix up the terms, so what was once "medium dark" becomes "dark". Her designs are beautiful, and well worth the extra work to decipher the directions, but I just wish it were more clear to begin with.
