Right, here goes..
Insert the first clip behind the rubber, in line with the join in the two windows. The reflection is complicating things a bit here..
Then put the second clip in as shown..
Start by putting the bottom of the blind in..
Pull the top of the blind down and tuck it under the clip..
Once in, gently push the front of the clip upwards which will make it more secure. In this picture, hold the front of the clip and lift upwards which will push the back down behind the rubber..
Same with the other clip..
Once in, check both clips are feeling fairly secure..
I actually moved the second clip along a bit and wrapped the label round on itself to 'hide' it a bit..
Hope that explains things a bit! As I said before, I still don't know if that's the right way, but it seems to work better with the clips this way up! If anyone knows any better, feel free to contribute. The rear ones are straightforward compared to these, so I'm sure you'll be OK with them.
Good luck again!
Paul.
