*+tweelingen design* So, you send your customer a sheet of paper and hope they can work out how to fold it correctly before adding the cord to form the shade? Wow! What a rip off. Why don't you have it come with the folds already pre-formed, so there's less chance of anyone stuffing it up and making a mess of the paper? And for this, you charge $85? You don't even say which nations currency this $85 applies to but regardless, that's way too high for a piece of double sided paper, a cord and what else? No information in this video and nothing additional on your website. Oh well.., shame. No customer here in New Zealand. Yeah, I know you don't care.
