How Do I Feather in Illustrator?
Adobe Illustrator is premium software for creating original graphic design works. Illustrator allows you to draw graphics by hand or using native tools, then add effects to enhance your design. Feathering the edges of objects in Illustrator is an effective way to soften the graphic or image. Feathering adds a glow around the image by making the outer rim of the border semi-transparent. The feathering effect can be applied to most graphics in Illustrator with the exception of still images.
Open Adobe Illustrator. Select the document you want to edit by going to "File" in the main menu bar and choosing "Open Recent Files." Alternately, choose "Open" and browse for file on your computer.
Select the object or group to be feathered using your mouse or the target layer in the Layers panel.
Click "Effect" in the main menu bar. A drop-down menu will appear showing all the Effects categories.
Choose "Stylize," then "Feather" from the submenu. A small dialog box will appear allowing you to set the radius of your Feather effect. The lowest setting you can choose is 0 and the highest is 10. The higher the number you choose, the greater the impact of the effect. For example, selecting 10 means that the majority of your border becomes transparent when the Feather effect is applied.
