I've updated the Ideal Bookshelf "gift package," so to speak. Now, if you want to give a certificate for a custom painting as a gift so that the recipient(s) can pick their books later on, I'll mail you a card with the info on it, plus a postcard to show an example, all in a nice envelope. You can then write inside the card and give or send it to your friend.
If it's very last minute then I can still email you a PDF version of the card, no problem.
Also, if you proved me with the recipient's email address and the date of the gift-giving event, I'll email them a reminder a few weeks later, to make sure they send me their books. This seems to be especially useful for wedding presents, so that the couple has time to honeymoon and then settle down before working to compromise on their combined all time favorites ;)
