Thank you for viewing our Perfect Fit fitting video. We also have a part 1 which shows you how to measure your windows exactly how we would measure. This perfect fit fitting guide shows you step by step how to install perfect fit. We wanted to recreate exactly how you would install the blinds from start to finish. We haven't used any special tools, we have built the blinds and installed them just how you would at home. Our range of Perfect Fit Blinds are available here https://www.blinds-superstore.co.uk
