Creating a roll of parchment in GIMP

STEP 6: Bump map

Gradient took care of the disc edges, but what about the handles? We'll use a different technique for them. Make a layer called Handles bumpmap, fill it with black, select all the handle shapes, and fill this selection with white on the new layer. Keep the selection and apply Gaussian Blur using radii that give nice results.



Unselect all and hit the layer with ordinary Blur once or twice.

Go back to the Handles layer and make sure you're editing the textured layer, rather than the mask. Apply the Bump Map filter using the Handles bumpmap layer. Tweak the input parameters to get a rounded 3D look.



Now both the handles and the discs should look fairly finished.
