Bamboo blinds are among the most economical and versatile window treatments available. A very thin bamboo known as matchstick gives a rustic look to any décor, while a Venetian blind can give a more traditional look. True bamboo blinds are designed to keep out direct sunlight, but you can achieve more privacy by lining them with blackout liner, either permanent or removable. Bamboo shades can roll up to close or fold up to close similar to a roman shade. The process to add blackout liner is similar for both types; there is one difference with how you attach the liner.

Step 1 - Measure

Unroll your blinds face-down on a flat surface. Record the measurements of length and width. Take these measurements to the store to purchase your blackout liner and trim.

Step 2 - Assemble the Liner

Cut the liner to measurements you have for the blind, leaving them short ¼-inch all the way around. Cut the length measurement of your trim 1 inch short. Cut your width trim using the exact measurements.

Place the edge of your blackout liner inside the fold of your trim. Use your hot glue gun to apply your top and bottom trim to the blackout liner. Make sure the liner meets the trim snug against the fold. Your length trim should fit easily between the top and bottom trim.

Step 3a - Attach the Permanent Liner

For a roll up type bamboo blind apply a line of hot glue across the top of the back of the blind and press the top of the blackout liner onto the shade. Repeat this process along one edge at a time, taking care to keep the liner even. For a fold up shade, apply the glue to the top of the back of the blind. Then, one dowel at a time, run a line of glue on the horizontal dowels of the blind.

Gently press the blackout liner against the dowel to ensure adhesion. Make sure the liner is kept straight without stretching it too far. Use the dowels where the blind folds. Do not glue the vertical edges.

Step 3b - Attach a Removable Liner

The process is similar to attaching a permanent liner. Replace hot glue with sticky Velcro tape. Attach one side of the strip of sticky Velcro tape to the edges of the roll up blind and the other side to the edges of the blackout liner, where appropriate. You should reinforce the corners of the Velcro on the liner with several stitches at each corner.
