Mistakes happen to everyone. If you make a mistake there are several simple ways to rescue your project.
If an imperfection occurs on the front of your notecard, attach a piece of coordinating paper over the area and restamp the design on another piece of paper and add to the layered piece.
If the image you stamped has ink in unwanted areas cut closely around the image, add on top of colorful layering paper and glue to another notecard.
Before attaching embellishments or layers of expensive paper complete all the stamping on your project. If needed, you can easily restamp a design on an additional notecard and add the layers of paper and accents.
