One of the commonalities amongst the photos that I choose, especially for knits and crochets are images that show the product on a real person. I think that a human face, as well as a little context greatly helps a product photo.
Rachel (my sister in the ajoeynamedroo team) and I took turns taking pictures modeling the products. Rachel looks so great in all the pictures. This one is one of my favorites. It features Tilly the cat!
