A collage is a poster of pictures or words.

You can cut the pictures or words out of magazines, newspapers, photos, or
Printing graphics and images off the computer. Look  for images or words that
remind you of the person who died.
You might find a picture of the kind of perfume they wore or maybe of a person
doing something that they did, like running or sewing. Maybe you will find their
first name or the name of the city they lived in.

It can also be important to share your creation with people and talk with them
about it. Sharing your stories about the person who died will help you grieve and
allow other people to know them through the images you create and the stories
you share.  This can be helpful and comforting in keeping their memory and spirit alive.
