No problem. This question comes up so often I am surprised there is not a sticky or section in the library with photos on how to repair a strop. Yea sanding is easier if the flaps aren't too big....

Those look familiar and don't seem to be too bad. If you can't glue them you could carefully trim the flaps off and the use something like a pumice stone to smooth it all out, particularly the edges....

Don't worry you are not the first. Try a quick search in the Strop section for repairing a strop. There should be a few threads in there on the subject. Yea, avoid the damaged part until you get it...
