It is a cross stitch but it only uses whole stitches and it is
11 by 19 on 14 count AIDA cloth
With a 2 inch border the finished would be 13 by 21 inches.
Not too bad when the dimensions need to fit abt 15 X 20.5 inches. So I would need to adjust the borders, easily done.
It measures 11 by 17 on 14 count AIDA
and requires about a 2 inch border for final measurements of 13 X 19inches
Then I found this one
On 21 count AIDA it would measure14 w x 23 h Inches.
I'd have to start at the top and work down, hopefully I would not need to cut of John and Mary's knees.
