Preparing the Jersey
Consider the style in which you would like to present your jersey. Do you want the sleeves to be showing? Or do you just want to highlight the front or back of the jersey? If you want to display the jersey in its entirety, do nothing to it. If you want to pin back the arms, fold them behind the face of the jersey.
Use measuring tape to get the dimensions of your jersey. Measure it from the top of the jersey to the bottom and from one side to the other. Write down the dimensions. This will help you determine the size of frame you will be looking for.
Go to a store that sells frames. Wal-Mart and Target both offer inexpensive frames in a variety of sizes. Framing shops sell higher-quality frames that can be customized to your needs. Keep the dimensions of your jersey with you and use them to select an appropriately sized frame.
Buy mat board to use in the frame. Mat board is a type of heavy-duty paper much like cardboard that comes in many colors and can be purchased at national chain stores such as Dick Blick Art Materials or Utrecht Art or at local art stores. Many stores will cut the mat board to a certain size for you, so remember the dimensions of your jersey and frame.
Mounting the Jersey
It is easiest to work on the floor or on a large desk. Remove the plastic from the front of the frame if possible. If the frame has a glass front, remove the back of the frame. With the mat board in front of you, fit the mat board into the frame. This is to ensure that the mat board is appropriately sized. If it does not fit, trim it to size using scissors.
Remove the mat board from the frame once you are certain that it fits perfectly.
Attach your jersey to the mat board. You can do this with small pins or by sewing it onto the mat board.
Place the mat board and attached jersey into the frame. Replace the plastic front of the frame, or place the back into place again if you have a glass-frame front.
Using a picture hanger, hang the frame on the wall.
