Listen, I had to learn this the hard way. When I bought the pattern last year, the instructions on how to mount were not included and I found only one tutorial on line that was for a different clock face, so I screwed it up. If you stitch on 14 ct, get a clock that measures at least 11 1/2 inches. The measurements on the boxes are the total size of the clock, NOT the clock face. On 14, the clock face you stitch will be 9 3/4 x 9 3/4, it will not fit inside a 10″ clock. I kept my 10″ clock and I’m doing the second one on 16 ct fabric, should be good. Also, measure the center very carefully and make your hole for the clock stem before you start stitching. I used an exacto knife and cut a 5×5 square out of the middle in my 16 ct. This allows the fabric to sit all the way down around the base of the stem and it’s small enough that the washer and the nut that goes on under the hands will cover the edges of the hole. I used Fray Stop on the edges of the hole then stitched over them with full cross-stitches, nothing fancy. It’s nice and smooth and tight, it won’t come apart.
I hope you see this before you start! let me know if you have any questions!
