Can Old Pennants Be Restored?
 

I have a very rare and very valuable c. 1910 baseball pennant, but the felt edges are moth eaten pretty bad. Is there a company or person that can restore these or is it a lost cause?

Consult a local museum for a textile conservator that they would recommend. It will not be cheap, but if you have an historic item, it's worth it, as the condition will likely deteriorate over time..... They may also offer suggestions on mounts which can stabilize the piece. Good luck

It may not be possible to restore a pennant considering there is not a thread pattern to tie into, but I could be mistaken. In all my years of pennant collecting I've not heard of an effective resoration regarding the body of a pennant. I hope it is possible however. Can you post an image of your pennant for us?
