Things You'll Need
Graber is a name brand of blinds that come in a variety of types, such as cellular, venetian, mini blinds, wood or vertical blinds. These blinds come in an array of styles and colors. After continuous use, normal wear and tear can develop, but it is possible to repair these blinds yourself with a few basic tools.

Remove the blinds from the window and place them on a flat work surface.
Slide off the bottom rail--the long metal piece--from the Graber blind.
Cut the string with scissors and each cord should be double the length of the blinds plus the width. Feed the string through the hole of a sewing needle and push the needle through the opening in the cord lock and through each hole in the blinds. Tie a large knot in the end of the cord. Replace the bottom rail by sliding it back on. Shove the knot through the hole in the bottom rail and cut off the excess cords with scissors.
Unjam the pin in the cord lock with a flat screwdriver to release the blinds if they are stuck and will not lift or lower. Push in the pin with the screwdriver to unlock it and it should release.
Repair broken or damaged slats by repeating the above restringing steps. Only remove the slats before you reach the broken slats. Slide the new slats in between the ladder strings, and wind the string through the holes in the new slats. Tie a knot below the bottom rail and use the scissors to cut off any excess string. Replace the bottom rail.
Hang the blinds back on the wall and make sure they operate correctly by lifting and lowering the cord.
Consult the blind manufacturer to make sure you have the correct size string for the type of blinds that you have, because there are different widths.
