Instead I tend to make my own cards. A few weeks ago I was working on sending a package to our niece who was having a birthday and as I went through my stash of finished cards I realized I didn't have a single card for a child's birthday. I was pressed for time and needed to run the package to the post office so this is what I did....it's so simple.
Using the same wrapping paper that I wrapped her gift in I traced a blank card (or you make your own by cutting a piece of card stock in half and folding in in half). I cut out the rectangle and glued it to the front. Added a 'wish' sticker from my scrapbook stash on the front. Just like that my card was ready to go.
