You can make very realistic-looking tissue paper or cloth with polymer clay by simply pinching it very thin little by little. I like to try and see how thin I can make it. The nice thing about a tissue paper effect is that it doesn't matter if the clay tears (which it tends to do when it's so thin).
To make this package, I started by forming the clay into a cube. I didn't make the cube hollow. I just made and indentation with the end of a paintbrush. I also didn't make the whole puppy. Just the part you can see! To make the paws I pressed a few lines in the clay with a toothpick. The beautiful star pattern for the wrapping paper was made with star glitter. Confetti and glitter are great additions to clay projects. Just make sure you press them in firmly. I also made a cute little top to the box with a simple square and clay ribbon.
