Rounded Edge Effect Without Border
Here are some solid background images I created with the rounded edge effect. I didn't put a border on these backgrounds. I specified 0 in the Border Size field, and 8 in the rounded edge value field. You can create these images yourself with the Free Rounded Corner Maker located on the front page of this website. The settings are indicated on each image example. Change the settings to create the size or specific image you would like to create.
