I got an email about a link in one of my old posts. It was a link to a cut-out template that I had used to make the above Eldar Warpgate. This template was hosted on GW's site, but is no longer there.
After a bit of searching, I decided to reconstruct the template myself, using my finished gate as a stencil.
Below, you can see the cutouts. You can click on the images for full-size. As far as the material, I used 1/4 inch poster-board.
Have fun, guys:
