# SheetSkin Editor

Learn how to customize the appearance settings for sheets using the SheetSkin Editor in Spread Designer

## Content

You can customize the skin, the collection of appearance settings, for the sheet with the **SheetSkin Editor** of the Spread Designer. To launch the **Sheet Skin Editor**, from the **Settings** menu (**Appearance** section), select the SheetSkin Editor icon. Or from the **Properties** window with the sheet selected, in the **Appearance** category, select **ActiveSkin** and click on the button. The **SheetSkin Editor** appears with the Default skin selected. This figure shows a particular skin selected to illustrate the preview of that skin.

The left side of the editor allows you to choose the skin, and the right side shows a preview of the appearance before you apply it to the sheet. The first tab, **Pre-Defined**, lists the built-in skins that are already available and ready to use and customize. You can simply click on a skin name and see a small sample of the appearance in the **Preview** area. The second tab, **Saved**, lists any saved custom skins that are available. This shows any files that you have saved. You can then preview that skin and either customize it further or apply it as is. The third tab, **Custom**, allows you to create your own custom skin or customize either one of the pre-defined skins or a skin loaded from a file.
Click **Apply** to apply that skin with all its appearance settings to the sheet in Spread Designer.
