if you're making a sampler quilt ... especially one with tiny blocks like a Dear Jane ... fat eights can make more sense than fat quarters or traditional cuts off the bolt.
"fat" cuts are only half as wide as their regular counterparts, but they are also twice as high. that will often result in having more usable space from which to cut.
even though you're paying more than the per-yard price for a fat cut, you're still buying less of the fabric. if you think you might want to use that fabric again, then a fat cut makes no sense. but, if you know you'll only want that little bit and no more you'll spend far less overall for that particular quilt.
i have such an aversion to buying less than a yard, it took me a while to figure that out.
you know what they say ... fact is stranger than fiction. :lol:
