I also made a card to go along with my cute rabbit and carrots :). I had some leftover scrapbook paper from my February Calendar post, which had a ton of sweets/candy themed pages in it. I cut it in half and folded it shortways. I had some stickers for Easter left from last year (yay for keeping old holiday stickers, espeically Christmas ones :).
My only caveat ot using this method is teh card is rather large. As a result, the acrd doesn't fit in any conventional envelope. I have made my own envelopes for these, but I think I am just going to cut some off the top of the half to create a smaller card.
