Ok, here is what I got from the 440 x 440 pattern stitch count and using a 14-count aida cloth stitching over ONE square AND adding 3-inches to EACH side of fabric for mounting and framing:
Stitched area: 31 1/2 inches wide x 31 1/2 inches high
Fabric needed: 37-inches Wide x 37-inches High
That’s a pretty big pillow....
Oh, and don’t be discouraged, when you start laying out a multi-page pattern ( I lay my patterns out on the bed, but prefer laying them out in order ON THE FLOOR so I can stand and look down on it ( bird’s-eye view) the pattern does look much bigger than the completed pattern. I put an example picture of a WIP as an example:
The actual WIDTH of this is 14”, BUT my paper pattern is
FIVE and a HALF pages of 8 1/2” Wide (x 11” high!!) to stitch that 14-inch. So don’t be thrown by the largeness of the PAPER pattern versus the actual size of the finished cross stitch.
