MYshade Arch Window Shades Half Circle Blackout (Black, 24″ W x 12″ H)

Best for compact arched openings on doors where a discreet, cordless shade is preferred. The 12″ radius fits arched windows with radii from 6 to 12″. Constructed from durable non-woven fabric with a laminated aluminum foil backing, it delivers complete blackout and privacy. It can be trimmed to fit irregular arches, and includes accessories to prevent tilting or falling. Install is tool-free with strong double-sided tape.
Who it’s for: small front-door arches or transoms where easy, tool-free installation is key. This option is ideal for renters or homeowners seeking quick privacy upgrades without drilling.
Limitations: May be too small for larger door arches; trim-to-fit reduces available color choices and may affect blackout performance if not aligned properly.

Like other MYshade options, it uses durable materials and a no-tool installation with tape. It provides near-total privacy while maintaining light diffusion through the honeycomb structure.
Who it’s for: homeowners seeking a larger, bright-look shade that remains simple to install and trim as needed. Avoid if you require a deeper blackout for bedrooms.
