I found this on the Vickery website: 208 x 136 14 3/4" x 9 5/8" on 16 count Aida.

Just be sure you add enough fabric to each side for framing/finishing. The design size, if you go by the stitch count, is 13 x 8.5. I usually add about 3 - 4 inches to each side for framing so that would be a piece of fabric about 19 x 14.5.

That Michael Vickery is sure doing nice designs since he got over Celtic crosses. Tempting me!

The model was stitched on 14ct. White Antique Aida cloth with the stitch count of 208 x 136. If you use 14ct. Aida the finished size will be 14.9 inches x 9.7 inches. Don't forget to add 3 inches per side for framing. I would use a piece of 14ct. Aida 21 inches x 16 inches. Hope this helps. This is a cute pattern.
