Step 1 – Measure the window.

  • Measure the width of the window in three places and round the smallest measurement down to the nearest ⅛ of an inch.
  • Measure the height of the window in three places, and round the largest measurement up to the nearest ⅛ of an inch.

Step 2 – Remove the blind from the box and packaging.

Step 3 – Mark the positions of the mounting brackets.

  • Drill pilot holes slightly smaller than the screws that you will be using.
  • Align your brackets, and drill in the screws.
  • Repeat steps for all brackets.

Step 4 – Mark the middle point for your center support bracket.

  • Repeat step 3.
  • Insert the headrail end caps.

Step 5 – Mount the blind to the brackets in the window.

  • Lower the blind.
  • Attach the wand to the tilt mechanism.
  • Test the tilt function of the blind.

Step 6 – Mark the slat at or just below where the blind will stop.

  • Before you remove the excess slats, note which are the ladder strings and which are the lift strings.

Step 7 – Cut the ladder strings approximately 6” below the marked slat.

  • Cut the lift strings approximately 6” below the marked slat.

Step 8 – Remove the bottom rail and buttons from the stack of excess slats.

  • Insert the bottom rail into the ladder string below the marked slat in your blind.
  • Fold and insert the ladder strings into the hole on the underside of the bottom rail.

Step 9 – Use the lighter to blunt the end of the lift strings.

  • Feed the lift strings through the bottom-most slat and bottom rail.

Step 10 – Feed the lift cord through the bottom rail button and tie it off.

  • Re-insert the buttons into the bottom rail.
  • Repeat steps 9-10 for all strings on the blind.

Step 11 – Re-attach end caps to the bottom rail by pushing back into place.

Step 12 – Test your repair by raising and lowering the blind completely.

Step 13 – Adjust the string length.

  • Pull your tassel up the string, and tie a knot at the desired length for your pull strings.

Step 14 – Pull the tassel down over the knot.

  • Repeat this for all pull strings.
