Bedroom lampshade

I have been doing a lot of research into the lampshade I would like in our bedroom and I know that I would like it to look like this.

Of course, I found the crystals after I had a go at looking for the frames! I picked up the ribbon on a recent shopping trip and it cost £3.30. This frame set looks a good deal - the practicality of wrapping ribbon around the frame without it being a solid structure is worth bearing in mind. It might be that I have to rope the mister in!

So the actual lampshade I found in a local store cost £80, the cheaper I can collect all the pieces for. The better!!! My plan is to get it done in under £20. That's my ultimate goal!
