Deconovo Katerina Custom Blackout Cloth Curtains review

Deconovo's Katerina is a made-to-measure panel that makes sense when your windows are an awkward size and you want certified fabric in a child's room. Deconovo lists OEKO-TEX Standard 100 certification and SGS testing and says the fabric is safe for nurseries. The important detail is in the fine print: the 350 GSM polyester blocks about 80 to 90% of light on its own, and you need the optional Grayish White or Gray lining, which adds $30, to reach 100% blackout. You choose the header from grommet, double rod pocket, pinch pleat or webbing, each adding $20 to $25, plus optional memory shaping for $49. The headline price of $49.99 per panel is a starting point; Deconovo's own example puts a 50 x 84 inch panel with the cheapest options at $131.99, and that is before the lining. Panels are machine washable in cold water. Custom panels showed an estimated arrival 10 to 22 days out when we checked.
