I just quickly looked at the actual pattern (I had just looked at the fabric before).
I'm not taking the time to match up each panel but I think common sense would rule.
For example -
If I look at Panel4 on the quilt (How the Grinch Stole..w/red background), the cutting instructions are
10.5" x 7.5"
The picture on the fabric page
http://www.robertkaufman.com/fabrics...ADE-11224-223/
shows the width to be 7.5"
Obviously, you would cut the 10.5" the long way.
Then you're going to sew a 2" (cut) olive strip around the whole Grinch picture.
You take the UNFINSHED block and do the postage edge thing (personally, I'd just use a wave rotary cutter).
And the whole thing gets fused to the background piece that measures 12.5" x 15.5"
All the blocks end up the same length (15.5 UNFINISHED), except the 3 thinner middle ones which have an UNFINISHED width of 9.5". while the 6 outer ones are UNFINISHED at 12.5".
