Lay four popsicle sticks next to each other horizontally.
Trim 1" off the top of two other popsicle sticks. Glue one to the horizontal popsicle sticks to hold them together.
Glue the other about 1.5" away from the first.
Cut another popsicle stick in half. Glue half to the horizontal popsicle sticks. This will form the support for the chimney.
Trim the round end off the other half of the popsicle stick. Glue across the top of the two vertical popsicle sticks. This will form the window.
Paint trains and wheels as desired.
Cut out a small triangle for the front of the train and a chimney shape from felt or other material.
Glue each wheel to the bottom of the train.
Glue a popsicle stick across the wheels, trimming if needed.
Glue the chimney and front piece in place.
Glue the picture to the back of the train, in the window space.
Glue a piece of twine, folded in half, to the back of the picture.
Glue a piece of felt over the border of the photo to finish.
Add any decorations, like mini wreaths or Santa hats, if desired.
