For the birthday one on the left - I created a happy birthday element by pairing two fonts, printed a large U which I coloured using colour pencils, a #2 to complete the greeting and continue with the graphic nature of the card and a birthday cake (downloaded from here) embellishment which is also printed and coloured with colour pencils. For the Valentine's card on the right, I used an initial font (Cheltshire Initials) to create the "LOVE" decorative element and added a printed heart embellishment - all coloured with watercolours. The backgrounds are printed as well using a stippling digital stamp that I downloaded off of my sister's blog.
So a card created using digital elements that has very much a handmade look!! Valentine's is the next "big thing" and I am ready with a card for my DH!!
