Thanks, Ingrid and DorothyDot! I may well write to Schoolhouse just to see what they say. Looking at other fairisle patterns doesn't always help, since when they say "1 skein of this" and "1 skein of that" I can't tell whether the whole skein will be used or only a fraction.
I have a lot of fingering weight odds and ends in my stash that I'd like to use in a fairisle design, which causes my problem -- do I have enough of each to carry out the design? You're right, Dot, I could change the colors as I run out of each one and that's probably what I should plan to do.
Anyway, I really appreciate your suggestions!
