I don't but I know they make skylights with built in blinds that you can open and close with a remote control.

Check to see if your skylights have a manufacturer's name on them. Velux and others make shades for their units.
Perhaps, if yours are old models, you could look at those and have some made.

A shade with catches so that the cord ran across the skylight could close it,just as do shades that can be pulled from bottom to top.

I have 2 in my kitchen extension with pleated shades which operate with the same pole that opens the skylights. I ordered them at the window place when I purchased the skylights. I closed the shades today and I won't open them before fall unless I open the skylights to release the heat. The shades make a huge difference. I have 3 skylights on the top floor, none of which have shades and you can feel the heat as you walk under them.

If you have the make and model of your skylights then the window place will know what to order. Otherwise take detailed, accurate dimensions to the window place.
