Every release of Adobe Illustrator attempts to incorporate new tools based on the requests of its customer base. Users wanted the ability to easily make scalloped edges in Illustrator and Adobe complied in Creative Suite 2 (CS2). Adobe Illustrator CS2 introduced the "Scallop Tool" along with other liquefy tools to allow designers to create scalloped edges by clicking and dragging anywhere on an object. The tool allows full control over the size and intensity of the scalloped edges. You can add scalloped edges to anything in a few simple steps.
Open Illustrator from the "Start" menu or desktop icon.
Open the project you want to work with from the "Open" link in the left pane of the welcome screen.
Click and hold on the "Warp" tool located directly below the "Rotate" tool in the left column of the toolbar.
Select the "Scallop Tool" from the expanded menu.
Double-click on the "Scallop Tool" icon to open the settings dialogue box.
Adjust the "Scallop Tool" to produce the desired effect. For example, adjust the width and height to determine how large of an area is affected on each pass. Click "OK" to apply the changes.
Position the crosshairs of the scallop tool near the edge you wish to scallop. The scallop effect will move toward the crosshairs, so position the tool according to which direction you want the scallop to point.
Click and hold the left mouse button. Drag the mouse in the desired direction to produce the scalloped edge.
