Indicating "no gifts" after invitations already printed
Ok, so I have party invitations for my son's graduation open house already back from the printer, and to be honest I never felt like the party invitation was a solicitation for a gift, seeing as how the food is served 5-7, the band from 8-10, and the bonfire 10-midnight. I just wanted people to come celebrate with us and my son. HOW do I indicate now that no gift is necessary so that people do not feel obligated? I am planning on mailing the invitations out with the announcement (that may be a "no-no" too, I don't know), so should I also include a separate little card of some sort reading "no gifts please" ?
