To install Home Decorators Collection Cordless Cellular blinds, start by measuring the width and length of your window frame. Then, choose a blind size that matches these measurements or trim the blind if necessary. Next, position the brackets at least 2 inches inside the top corners of the window frame, ensuring they are level with each other. Use a pencil to mark where the screws will go and then pre-drill holes for the screws. Secure the brackets in place by screwing them in tightly. Finally, attach the headrail of the blinds into the brackets and snap it into place until it locks securely.
