DIY Sewing Tolerances, Wall Mounting Structural Disclaimers & Safe Installation
Calculations generated by our window sizing calculation tool serve as architectural approximations based on industry-standard workroom formulas. Because textile elasticity, ambient room humidity, and fabric shrinkage vary across natural linen and cotton weaves, final fabric behavior is subject to our published Fabric Tolerance Disclaimers (±0.5 inches).
Our Structural Mounting Warning mandates that homeowners and contractors verify the structural integrity of wall framing, stud locations, and mounting hardware before hanging heavy curtains. Never install heavy drapery or tension rods into unanchored drywall without appropriate weight-rated toggle anchors.
