What makes our louver sleeve stand out? Custom Canvas is specially designed. Unlike typical blinds, it features no holes in the middle of the louvers. Ladder cords run through the back of Custom Canvas via the “Lip.” Textile products are inserted into the clear-channel louver sleeve. The louvers have ridges for reinforcement, which helps reduce textile movement and prevents sagging or bending. When closed, the Lip overlaps the louver above, ensuring a seamless display of the inserted textile and total privacy.
