Star Correct an edge Error?
Back to my "edge wrap" technique. I've got the system down pretty well as far as cropping the image to a regular polygon. I then am able to select edge strips from each side and flip, rotate and apply to the appropriate polygon edge for future canvas printing and wrapping each "tab" edge around the pine strecher frame to be stapled on back.

Here's the problem....solution ought to be simple, I'm sure but I haven't figured it out yet. If i goof up and apply one edge incorrectly or size it wrong and then save the finished image as a GImp image; how can I later go back to the file and just make an active rectangle (or whatever) and crop out that bad tab and then replace it with a good (correct) copied/flipped image or layer?

ie, I want to crop off the far left tab and replace it with a correctly sized one.

RE: Correct an edge Error?
First thing I noticed, the starting image is not symmetrical, not 100% necessary but symmetry makes it easier.

Going back to the original theme, if you are happy with the 'mirrored' tabs, look at making short cuts, and automate the procedure as much as possible.

So I would say, once symmetrical, this procedure

Set up some guides to form the area of a tab to copy from:
1. Make a rectangular selection of that area
2. Copy selection to clipboard
3. Move the rectangular selection
4. Paste from the clipboard
5. Flip the floating selection
6. Anchor the selection
7. Rotate the whole layer

start back at 1 and keep repeating until complete.

Here is a video which might make sense of the above,
A bit rough but tomorrow (Friday) is a busy day and it might not get done.
