One question I was asked a lot last year (2007) was "How did I attach the ropelight around the window, and get it looking so straight?"
What you will need:
- Screws or nails - make sure they are stainless steel or similar so they don't rust and stain the wood or the ropelight. I used screws.
- Wire - I used 2mm stainless steel fencing wire.
- Clear cable ties
- Ropelight or string lights
- A window!
As per the photo drive in the screw or nail a little away from the corner on both sides of each corner.
I don't see any reason why you couldn't put the screws or nails into the side of the frame.
Now attach the wire onto one of the screws and run it around the frame making sure to wind it
Then finally cable tie all around at the screws and any other place required to hold the light straight.I put 4 on each side and that seem to work well.
This image shows what can happen if there aren't enough cable ties to hold the light straight.
As you can see it looks a lot neater when done correctly.
* I would only put small nails on the corners as they aren't as heavy as ropelights.
