Similarity.

Debby brought along this fabulous book.It had given her inspiration for her butterflies.The photos are so very detailed.

While leafing through Sally noticed the similarity between this and her drawing on her tablet.

As you can probably read ,her drawing was of a barrel cactus.

     It's a really good drawing using a drawing app.Good if you don't want the hassle of carrying lots of paraphernalia and are short on space.
