I have two cellular shades mounted inside casement windows and they stop before the handle on that lower ledge ( the equivalent place where you mount them on top) and it works fine. But I am unable to keep a screen in these windows. I love my casement windows but they are a lot more difficult for window treatment.

Have you considered changing out the handle? You can call the manufacturer and see what's available for your window, but the T-handles listed below are universal, so they may fit.

Thanks for the replies.

We dont use the window much, and the first thought was to just remove the handle and use when needed. Unfortunately, the crank assembly itself sticks out too far

We have collapsible handles, so the handle part is basically a non-issue, its the "platform" that holds the gearing thats the issue.

I know who makes the window hardware, perhaps I can find something. Otherwise Im still at square one :) Maybe Ill just buy a cheap plastic blind from HD and test it out to see how it looks/works.

Do you have your heart set on blinds? How about cafe curtains? Mounted inside the frame you'd still see the nice trim and the casement handle would become a non-issue.

Was thinking cellular shades for the energy efficiency perks plus more of a modern look (the house is contemporary, and the nursery is painted in a modern-like pattern).

We had verticals there, but Im just tired of verticals....I like seeing the window trim instead of valances.

You may find that you want full coverage of the window to prevent any light coming into baby's room - I found a dark room good for sleeping babies!
Congrats on soon to be mama!

There is that side of things too!! In fact, we set my sons nursery up just for that situation........sheer curtains and then thick drapes in front. I still like the cell blind idea, but Im leaning more towards outside mounting them just to make sure no light gets thru.....the new nursery is in the front of the house, which gets the most sun.

Mama to be says thanks!! Im just the handyman/husband trying to finish the room before mama to be goes crazy.

Congrats to the daddy to be also!:) I neglected to say, that I have casements & the slider windows in both of the last 2 houses I have lived in, although not in the same room. In this particular case, I would 100% rule in the favor of function over design & do outside mount on both windows. I have had both the casement handles - the newer folding handle still protrudes as you described. Order your cell shades long enough to go below the handle so the shade covers the sill in the down position. My experience - the shade will gently go over the handle.
I am one who likes to sleep in complete darkness!!! On a casement window in my bedroom, in addition to the cell shade, I have a cheapie blackout vinyl shade inside mounted that I pull down inside the cell shade (I have a close inconsiderate neighbor who is semi retired who keeps his spotlights on). I am an adult baby who needs to go to sleep before 2:00am!
Mama & papa will both be happier if baby sleeps / naps on your schedule!
