I
often use clip art from openclipart.org or clker.com. These clip art
are free and public domain.
I
found Thanksgiving turkey on clker.com, Thanksgiving Turkey by Kara78.
I
changed background with Inkscape, orange color #f26011.
Then I used Gradient tool to create a color gradient.
I
also made coloring page. I changed all colors to white, except
stroke paint of course, which stays black.
