I hope this cross stitch design gets your "seal of approval". I based it on a painting I did of a seal pup looking through a hole in the ice and thus it is ideal for an aperture card with a round aperture.
This is what it looks like made up with a trifold card featuring a suitable background. The card blank will also soon be available to buy, but for the meantime you can obtain the chart and get stitching.
