[Window blinds]

Thinking of replacing curtains with blinds, can I buy ready made casements to hold them in place or do they need to be custom made. Quite like the wooden box type casements you see on some boats.

Thanks for all the comments and advice, loved the casements, but sadly the galley is fitted up to one edge so no opportunity to fit anything that opens in. Really want to install glass into existing hatch, not only will we get light all the time but it will also avoid having to carry and slot in a filler panel.

That's exactly what we have at present, But the acrylic gets scratched, not great when wet or cold and when removed we loose the light. I would really like to get more light on a permanent basis.

Thinking of fitting windows into the side hatch to allow more light in  when it's too cold to open the hatch doors. Can this be done easily and are there any issues?
