How To Send A Puzzle Card

Connect instantly with the ones that matter most with neat personalized E-Cards. Sending an E-Card is easy, just follow the instructions at each step along the way. We also want to let you know that the cards are stored in a non-indexed directory so only you and the recipient will know how to find the card. This directory is also pretty secure from spammers, so send your card knowing you will not end up on any junk list.

After you have completed the card, you will be shown a preview. If you do not like your card, you may edit it and then send it, or just cancel the request. The recipient will receive e-mail advising where to find the card.


Step 1: Pic A Picture

Please select a picture from the list below using the little Radio Button selector. You may only pick one picture per card. If you want to see a full size image of a picture, please, just click on it.
