Always measure the window in three different places for width/drop.
Ensure there are no obstacles around your window or within the recess that may prevent your blind from functioning correctly. Obstacles include telephone sockets, decorative rails, decorative window frames and skirting.
When deciding where to place the blind within or outside the recess take your window handles into consideration as they may affect the how the blind works.
When installing blinds adjacent to one another provide at least a 1cm gap between each blind to make sure that each blind can work separately.
Please note if ordering wooden venetian blinds and your order is for blinds to be made exact blind size. Then the blind headrail will be provided with wooden returns to go with the top wood cover valance. This is an optional extra that hides the blind headrail, and the ends. It is your choice if you use them or not. Click here to view images You would only use the returns if the blinds were to sit outside the recess free of window returns, and obstructions. The blind will not change in size, only the wood valance. If you decide not to use the returns then simply cut the valance square to the width of your head rail with a small tenon saw.
