This saved my drilling holes in my new wall in my new office we had built!!! i tried it with little sticky pads and foam pads. as long as the blinds have been cut to the right length, it all works great!! 

I had seen previous larger square items like this in dunelm shop however i thought it might be a little ugly with a huge square piece of plastic on the wall so i set out to make one that was the smallest i could make it but do the same job. I printed it in colour for the photos however if i printed this in White it is nearly invisible from view. TO be honest this is nearly invisible from view when the blind is up even in turquoise.
