I just saw Judy Mathieson's book, Mariner's Compass Quilts—Setting a New Course, on sale for $5 at the C&T online clearance sale. Even with shipping, it's a steal.
And a great book.

The center of my avatar quilt is from her first book - the Costa Rican Cartwheel block.
MC's are my favorite block - love drafting them.
I don't know if it's still available but she has a companion CD with scores of different compasses that you could print out in any size/dimensions you wanted
It's a little quirky when printing - this was ca. 1998 - but I use it all the time.
I wish she'd reissue it (with some technical upgrading).
I'd buy it even though I have the original.
