Make a blind

CUTTING MEASUREMENTS How you measure your window for a blind is determined by whether the blind is to be fixed inside or outside the window recess. A blind inside the recess is usually fixed to the top of the window frame, or to the top of the recess. When measuring up for one fixed outside the recess, first decide where the blind will be hung from. This will be the starting point for the drop measurement. The width is determined by adding 10cm to the total window width.

INSIDE THE WINDOW RECESS Measure the width of the recess at three points. Subtract 1cm from the smallest measurement to get the finished width. This ensures that the blind has room to move up and down. For the drop, measure from the inside fixing point to the windowsill.

OUTSIDE THE WINDOW RECESS For the width, measure the width of the recess and add 10cm to give a 5cm overlap on each side. This prevents light coming in at the sides of the lowered blind. For the drop, measure from the fixing point to just below the windowsill.

Measure your window. Add a 1.5cm seam allowance to either side. Add 6.5cm to the overall drop for a 5cm turnover at the top and a 1.5cm seam allowan
