Is there a way to blur a part of a layer by another layer?

Layer 3 (transparent layer with blur effect)
Layer 2 (the template which makes the T-shirts look like real - 30% semi transparent in multiplying mode)
Layer 1 (T-shirts in various colours and designs)....snip.

No replies?

Obviously you cannot blur a transparent layer. Nothing to blur.

The way is really to adjust your jaggy logo before planting it in your template.

Then it depends on your template. You duplicate a layer, blur it, add a black layer mask (fully transparent), paint in the layer mask with white to expose the blurred areas.
