The page with the free printable Valentine cards is here at this link.
They are not in any particular order so be sure to check all the way through so you will not miss the perfect card for a special person.
They range all the way from cards for kids to send to kids, cards that are funny and some that are pun-ny, all the way from sweet and sentimental to deep and loving.
Although they are all free, be sure to read the page when you choose your card(s). Some already have the sentiments printed on them. Most of these you just hit Print. You do not download these. To get the capability of either adding your own text to some of the cards, or to download, you need to pay a small annual fee and join the site. It's well worth it but you need to know that this is an option. There are dozens that can be printed directly and without a fee.
This is part of my series (1/15-2/14) of Valentine projects.
For other projects in this series, just look along the right sidebar for the label "Valentine Projects." I will post only tips that do not require knitting, crocheting, machine sewing, tatting, embroidery, or any other skilled technique.
If you are feeling lazy, check my Etsy shop for items for your gift list.
