My new favorite site for Mother's Day e-cards is Ojolie.
The cards are both beautiful and understated.
Here's what the artist/owner of the site, Frederikke Tu, says about her work:
"Our ecards are my work of passion, taking weeks of painstaking - but fun and satisfying - work and attention to detail to complete. First I hand paint many parts, and then the scanned images are combined with Flash animation to create a visually stunning story."
The ecards are not free, but for a 1 year subscription it will cost you only $10.
My favorites are definitely the animated origami cards, but so many of the them are absolutely gorgeous.
