Hi!
We just did this.... we invited over 50 people to our Jamaica wedding via e-mail & our wedding website. We got A LOT of positive comments... however, we did run into a "handful" of people who did not have e-mail. Grandmothers, old family friends... so I am printing my own invites now for them. I am making 20. Now that I am making these, my family is saying they would each like one for a "keepsake". So I may make a few more...
Good luck!!
