It's really easy to add and adjust the size of the cliparts in our Design Lab!
First, add a piece of the clipart using the "Design" tab at the top of the design panel. Browse through the cliparts categories to find your desire cliparts. Click to select.
Once your art has been added, a black colored circle may appear. Click on the circle to select the color you like.
To adjust size, simply pull on the lower right hand corner of the image. The icon should look something like a backward "L", the further you pull away from the center of the image, the bigger the image becomes. to scale down the image, simply push the towards the center.
Repeat the above steps to add and adjust more clipart. If you need to go back and adjust a previously added piece of art, simply click on it to select it.
