Similar to this, I recently got 2 pork picnics (was supposed to be one shoulder and one picnic). The skin was still on so I had the same idea as you: what to do with it.
Cracklin's.
Hmm, didn't want to do it outside (too cold) so I found an indoor method.
Long story short, after the first four "finished" pieces, I tossed the rest. The flavour was great but it was like chewing on a rubber boot.
Obviously not the right method was used in my case but it is a suggestion depending on your situation/locale.
