: Gaussian Blur in Illustrator CC Problem I am using Gaussian Blur in Illustrator CC. However, parts of the glow are outside of the line art. How can I delete those parts? Before I applied the

You can use a clipping mask.

Here I have 2 shapes. The bottom shape has the blur.



Select both shapes and go to Object -> Clipping Mask -> Make



In your case you would need to make a duplicate of the shape that will clip the blur layer.

Don't Use Gaussian Blur.

If you want the blur to only occur inward on a shape, use Effect > Stylize > Feather rather than the Gaussian blur.

Gaussian blur takes the value you input and blurs half of it outward and half of it inward. It essentially blurs the edge of the object.

If you only want inward blurring using the Feather effect does that. Just use a smaller value than you would use for G-blur. Feather constrains the "blur" to the bounding path ensuring no generated pixels go outside the original shape.

Not really sure why you're doing it this way at all but if this is how you want to do it than use a clipping mask to remove outer areas. I'd use gradients instead. Anyhow if you're set on this then here's your bottom hand thing:

Three pieces:



Align the two:



Select, right click, make clipping mask:



Position back in place:



But really I'd probably use gradients instead of blurs.
