How to apply selection "frame" to another layer

[Gonz]

Hello, I'm newbie and probably this is a silly question.

I want to replace with a texture an area of a graphic with a flat color, so what I'm doing is selecting the area by color, mask it, invert mask, and place the new texture below in a new layer. But since the texture layer is bigger than the graphic,  I don`t want to keep the whole new layer, just use "the frame" of the area of the graphic I masked, and apply it to the texture layer . Otherwise the texture layer will be visible in some parts of the graphic. I have been looking for some tutorial but could't find anything. Probably I didn't use the correct key words... Thank you.

You can save the selection as a spare channel Select > Save Selection > As Spare Channel and then you can load that section any time you want from the channel Panel by right clicking on the Spare Channel and loading to a pixel selection.
