The Plan Book Special Edition is printed on heavyweight paper and darker drawing lines. It comes shrink wrapped and has newly designed front and back covers, also on hard, heavyweight paper.
Earlier I had said that the Special Edition is hardcover. It’s not like textbook hardcover, but more like very stiff paper.
Here are some pictures comparing the thickness of the regular vs. special edition, and of the back cover. A preview of the inside has been posted earlier.
The Special Edition is now available for purchase at ckhollidayplans.com for $134 plus shipping and handling.
