I understand the love/hate and avoid them whenever possible but sometimes they are just the perfect project. I have friends who have done wonderful things so I am just shamelessly taking this idea from them:
Have the original signatures/jersey transferred onto fabric -- make sure everyone understands what is happening and you don't get a reversed image! Cut/frame the original jersey into a wall piece and include it along with the top. You can frame with all fabric or a mat that can in turn be written on, for example basically the card with the to/from and personal message.
