I vote for:
"Yes! You own the sheet, do whatever you want with it."

Only because it is yours and you have the right to do with it as you please.

The only issue I do have is the motive of selling in the future. It has to be clear that they are hand cut from a sheet. Even if you disclose this, there is no guarantee the person buying from you won't flip it without disclosing this information. Eventually someone may try and get a TPG involved and they will say it is trimmed.

I am a strong believer of if it is yours you can do with it as you please within moral/legal limits, in this case not doing it with fraudulent intent.

EDIT to add: I wouldn't do it. I would frame them.
