Rehearsal dinner invites

Hi, so I wanted to get some ideas on how y’all sent your rehearsal dinner invites! I have extra paper that we ordered from Amazon and could just print the extra rehearsal dinner invites on. We could do online invites but I figured if we already had the paper we could just print them. For context we are doing our entire wedding suite ourselves with deckled edge paper and the extra we have is also deckled edge. We thought we could just add these extra invites in with the entire wedding invitation suite for the people invited to the rehearsal dinner. The one thing that I am thinking is what if it’s too much and they forget? Or I don’t know discard this invitation? I could just send it separately maybe a few weeks after but honestly I am not sure. Advice is definitely appreciated!
