Step 1— Assembling the Cornice

A.    Measure Your Window Size

 Measure the width of your window including blinds, curtains, or molding (whichever is the widest) and add a minimum of 1 inch per side, or more, according to personal preference.

B.    Cornice Width Adjustment.Size

Example:                                74” window + 1” on each side = 76” cornice                             

 You will need to cut one of the 16” extensions to get the 76” length. You will cut 14” from one 16” extension. To cut draw a line, using a ruler as a guide, from top to bottom on the back (flat side) of the cornice. A hacksaw, electric carving knife, or retractable utility knife extended about 4” may be used to cut the polystyrene forms. Use a slow up and down sawing motion rather than trying to slice the piece
