Invisible ink for RSVPs

You could number with a regular pen

I used a sharpie and wrote small numbers on the back top right corner

I just used a regular pencil on the back. Majority won't notice. The few that do know why it's there and don't care

I wrote the return address on the RSVP envelopes. I didn't think about the black light pen and I didn't want to number with a regular pen and have someone say, "hey, why are we RSVP #85?"

FWIW, out of our 85 invitations, not a single one came back without a name.

Oh I never thought to do something like this! Great idea!

I was worried about this too! I ended up just filling in the names on the rsvp cards. I did it with fancy cursive handwriting so it fit right in with the rest of the invitation set

We did ours with a regular pen. So far everyone has put their name though

Ok sorry y'all I'm slow I guess....never heard of this can someone explain.

I got a blacklight pen from Amazon and it worked great

@FMHayes People check off the "yes" or "no" on their RSVPs, but then don't fill their names out. Because of this, a lot of people have started to number the back of their RSVPs.

The back of my rsvp was white. I used a white paint pen to write small number on the bottom right back of my Rsvps. No one else would notice but I could see if the light reflected on it. I had about 5 that came back with no names-so it was helpful!

I won't be much help but I found this idea on Pinterest. So many start there.

I wrote mine super small on the bottom right corner. I'm glad i did cause i got a few back with no names

I had good luck with these, but they are currently out of stock: https://www.amazon.com/gp/product/B01AJDOBIY/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1
