The Origami Forum

I participated in an origami trading card exchange. It was my first time so I asked around about it. I learned that you can never sell them, only trade or give them away. But which ones can you give away, only the ones you make or also the ones you get from the exchange?

I ask because there's this card I really wanna give to a friend I'm seeing tomorrow but I don't wanna do it if it's offensive somehow with the person that gave it to me.

PS: I would really appreciate an inmediate answer since tomorrow I'm seeing my friend .
