A photography collage can be accomplished by anyone, from professional photographers to children. Take your camera into an area that has an array of fall colors, such as the local park or along a hiking trail in the woods. Take photos of appealing images, such as a pile of leaves or a cluster of acorns hanging from a tree limb. Ensure that the photos contain many colors, and take pictures from up close and far away. After you've had them developed, create a collage using all of the photos. Cut some of them so they are small, and have some of them enlarged. You may want to frame the photo-collage and hang it in your home or office.
Creating a leaf collage not only teaches children about the many kinds of trees but also gives them a chance to make an art piece. Take your little one to a park or a heavily wooded area, and point out a few types of trees, such as oak, maple or poplar. Together, collect a variety of leaves that differ in color. Spread out the leaves on a table or desk. Have the child place the leaves all together on a piece of poster board. Together, glue the leaves down to create a collage.
With your child, create a collage using some of his drawings. Have your child draw and color, using crayons or markers, a selection of fall images, such as an acorn, a pinecone or a yellow maple leaf. Together, cut out each autumn-related drawing, and paste the images on construction paper or poster board. This artwork can be a keepsake that you hang in your little one's bedroom or frame and put in your office.
