"Quilt in a Day" is a myth! The time frame that is..... not the pattern. I can't imagine doing a quilt in a day. ANY quilt! Unless a day = 24 hours straight, with no cooking, no eating, no phone calls, no bathroom breaks, (!) no emergencies - little or big, no husband or kids in the house or anything else possible going on in the house. :-)
I don't know about the pattern.
