Why not showcase that special Valentine's card by mounting it on a frame? White canvas stretcher frames can be easily found in a variety of sizes in craft stores. All you need to do is cover it with an approriate amount of fabric and use a staple-gun to attach it to the back of the frame. You might need a second pair of hands for this, so that the fabric is nice and taut. Using a zig-zag stitch sew a trim around the card, then stick it down with some fabric glue. Finished!
