I made my thank you cards for my wedding and my bridal shower and I thought I would share the ones from the shower. I got the clip art frame from graphicsfairy. Graphics Fairy has every kind of clip art you could imagine! Here is the image. I just copied and pasted it into a word document, shrunk it to size, and then printed it.
Click on it to get it in its full size and then just copy it to your computer. I put 2 per page and cut them out, but you can make them as large or as small as you like! Have fun with it. I stamped the back of each card with a custom stamp from etsy too.
