Greebling attempt for the Defender.
Trying to greeble for this model is interesting in that everything seems to blend in with the background of the ship. So multiple layers are required to raise the surface features of the ship (as mentioned in an earlier post).
What is done is you cut out the desired surface feature and glue it on top of another blank (or not so blank) piece of cardstock. Next you follow the outline of the desired shape with your knife.
For raised features on a feature you've already cut out you could do it a couple of ways:
#1 you could reprint the feature (wasting additional toner and ink) or you could #2 cut out the feature you want to raise (I opted for option #2).

As you can see in the image above a "t" shape was cut from the central section of one of the pieces. Another piece of cardstock was cut out and added to the cut out area where the "t" shape piece was removed on TOP of the new piece of blank cardstock. In the lower right hand corner of the picture you can see another piece before cutting is done.

The lower right hand piece added to the card stock backing with the desired pieces for raising cut out located to the right of the piece.
Next the pieces are cut out.

The main pieces that had the cut out area are white due to having a matching piece of cardstock cut and fit to the empty area.
The pieces that are to be raised are glued on top of the main pieces.
If you notice the edges of each piece have been colored with pencil. You could also use a black marker as well for this ship. This is done to cut down on glare and have the pieces blend in better with the ship since everything is in shades of grey, black, or white. This is done BEFORE you glue the pieces to the model.

I hope this helps some of you out there trying to make this ship.
