Can I use an overlay clipart to create a greeting card that I sell?
Yes, for example, you can include an overlay in a greater card design, as long as the end result of that design is significantly different than the overlay you originally purchased. You may employ various methods and skills to create a significantly different design, including adding textures, adding unique hand lettering or illustrations, adding photos, using various Photoshop add-ons, adding additional graphics, adding text, etc. However, you are not permitted to purchase an overlay and put that overlay on a card unchanged.
End Products must be significantly different than the original Item and require time, effort, and skill to produce. End Products must not be used or sold in a way that is directly competitive with the original Item you purchased. End Products must not redistribute the original Item to any third parties in a manner that allows for the extraction of the original Item.
