Here are the three versions of this one cute little lamb:
Lamb in Sweater on a Floral Op-Art Background
Lamb in Sweater on a Polka Dot Background
Lamb in Sweater on a Checked Background
These images are available in sets of 12 of a design or assorted - 4 each of the three designs in the Op-Art Sheep Series. You can find them on the Shop Page of my website.
The lamb is of course wearing her "Lamb Sweater" which you can make for your favorite pooch (A Dog in Sheep's Clothing) - an easy to knit pattern also available on my Shop Page for instant gratification PDF download.
