E Birthday Cards

On June 20, 1999, my birth son and I were reunited. I want to send him a special e-card for his birthday. This was one of those adoption reunions that is so wonderful that it makes you cry. Proud biological mother? You bet!

I am looking for free, printable birthday cards online, if they’re Dora the Explorer themed you’re my favourite person ever!
I have Paint, but I’m hopeless with that kind of thing.

I don’t want e-cards, just regular cards, and they have to be free, I don’t want to have to pay for a site subscription to download a card.

Thanks.
Lividuva, I’ve been to that site, but was unable to find birthday cards, I could only find thank-you cards and invitations, are you able to provide a direct link to the birthday card section? Thanks.
