How to Make a Cardboard Picture Frame
This frame is easy to make and can be decorated as simply or as elaborately as you like.
Measure the photograph you are going to frame and add 2 1/2 to 3 inches to each dimension. The number of inches you add will determine the width of the frame’s edges.
Cut out two pieces of cardboard. Each should be the cut to the dimensions calculated in step 1.
Use a ruler and pencil to measure and mark out a square or rectangle (the shape will be the same as that of your picture) in the center of one of the pieces of cardboard. The dimensions of this shape should be 1/4 inch smaller than the size of your picture.
Use a craft knife to cut out the rectangular or square shape from the cardboard. Cut evenly along the pencil marks.
Lay the piece of cardboard with the cutout window on a flat work surface and decorate one side of it. You can use markers, stamps, paint, crayons, glitter – whatever you like. Allow any glue or paint to dry thoroughly before you continue.
Determine which end of the frame will be the top and which will be the bottom.
Place the decorated piece of cardboard facedown. Use a ruler and pencil to mark three lines around the cutout window – one on each side and one along the bottom. Each line should be made 1/4 inch from the window.
Place a thin line of glue just outside (away from the window) of the pencil lines made in step 7. Also place thin lines of glue along the side and bottom edges of the cardboard. A glue stick can also be used.
Place the remaining piece of cardboard on top of the first, making sure that the edges line up evenly. Press the two pieces together, and wipe away any excess glue. Allow the glued pieces to dry thoroughly.
Affix a small loop of ribbon to the back of the frame with tape or glue and use it as a hanger. You can also affix magnet strips to the back of the frame to create a refrigerator magnet.
Insert the photo into the frame through the top.
