GIMP automatically saves all existing paths as clipping paths when
exporting to TIFF. Hence all you need is:

1. Make a selection around the object any way you prefer.
2. Choose 'Select - To Path' in the menu.
3. Export as TIFF.

Note that the selection should be quite clean. You can test this:

1. Convert the path to selection (from Paths dockable dialog,
right-click menu or the bottom toolbar).
2. Press Ctrl+I to invert selection.
3. Press Del or Ctrl+X to remove the area around your original selection.

That will give you an idea how the clipped object will look.

Alternatively you can run a desktop publishing app, create an image
frame, load your TIFF file and apply the clipping path.

Please provide a more elaborate explanation:

1. Operating system.
2. The file format of the image you are working on (better yet --
upload it somewhere and link to it), availability of layers/masks in
the project.
3. Paintbrush settings.

In that case you need to create a new group layer. You also need GIMP
2.8 for that.

Look at the Layer menu closely and at the small toolbar in the bottom
of the Layers dockable palette.

Oh, and the version of GIMP, of course.

Hi Alex,

Thanks for the response.

 I expected all of the visible layers to simply be moved
 as separate layers into the layer group.
 
 In that case you need to create a new group layer. You also need GIMP
 2.8 for that.

I am running 2.8.14
Perhaps I was too vague in my original question; I'll try to clarify.
I have tried it both ways:

1a.  Create new group layer (Layer/New Layer Group)
1b.  Layer/New from Visible.
  This creates an additional new layer as a sublayer of the group
  layer created in 1a, containing the visible layers I wanted as 
  sublayers, all flattened into the new sublayer as a single layer.
  The original layers are still present and independent at the top level.

2a.  Layer/New from Visible
   This creates a new independent layer containing the visible layers I
   wanted as sublayers, flattened into the new layer as a single
   layer.  The original layers are still present and independent at the
   top level. 

In neither case are the existing layers moved to become sublayers.
 
 Look at the Layer menu closely and at the small toolbar in the bottom
 of the Layers dockable palette.

I don't see anything there that is not also available via the layers menu.
There's a new layer button equivalent to Layer/New Layer, and there's a 
new group button equivalent to Layer/New Layer Group.  Plus the up, down,
duplicate, anchor, and trashbin.  Should I be seeing something additional?

still searching for a convenient solution...

I'm not sure why you are trying to do this. Perhaps I don't understand
what you are trying to achieve :)

To move existing layers to a layer group, click to select the first
one, then drag and drop onto the layer group, repeat for each layer.

There is no multiple layers selection in GIMP yet. This obviously
needs fixing, and some preliminary work has been done there, but it
was never finished. Hopefully someone will find the time to make it
possible.

 According the the manual:
 
 You can put layers to be added together to a layer group by making
 them, them only, visible, and using the “New From Visible ” command.
 All visible layers, outside and inside layer groups, will be added to
 the active layer group. 

I don't get what the author of this is trying to tell the reader.

I guess it is time for an overall review of the docs?

I know I can do it that way.
