Displaying three flying geese on the wall was very popular in the 1950s and 1960s - and you could use this flying goose template to do the same! It's a useful shape for seascape collages, too.
Here's a simple template that you can use to cut out shapes then put them together to make your own little penguin! Find some black, white and yellow/orange paper, then use the template and instructions to cut out and make your penguin.
