The pattern for the penguins is called "Hanging of the Lights". I purchased it at my LQS but I Googled it and you can find it several places online. I used Texture Magic for the tummys and I think it made them really cute.
The snowman is a Pearl Louise design -www.thimblecottage.com- I saw the wall hanging on a quilting forum last year and ordered the pattern. It may have been this forum where I saw the pattern. I used flannel for the snowman family and it was easy to do also. Thanks for the nice comments.
