Window treatment for half-circle

Hansi | Posted in General Discussion on

I have several windows in my house that have a half-circle shaped window above a rectangular shaped window.  The professional curtain makers who have made treatments for other houses in my neighborhood seem to handle this by making something that looks like a paper fan (except it’s made out of fabric, of course.)  Does anyone know how to do this?  Or know of a book that tells how to do this?   I haven’t seen this particular problem discussed in any of the curtain books I’ve checked out of the library.

Also, any other ideas for handling it would really be appreciated. 

Happy Sewing!

      Thank you!  What a wonderful link!  I've gone to not knowing what to do because of having no clue to having 3 great ideas to choose from.  I truly appreciate your time in posting this.

    If Jean's site doesn't give you ideas, and if you are adventurous, you could try to mimic outdoor orientations with a sunrise, sunset, tree painting, clouds, etc., on paper fans, maybe reversible, and move them around as you choose.

    Personally, I love to see the outdoors and wouldn't cover them at all except for privacy. They would look stunning with stained glass if you know the light pattern. You can make several insets, for lack of a better word, for each section of the half circle.

      I actually had to deal with these windows in my Master bedroom which faced East on the top of a ridge! The sun poured through the windows starting at sunrise and about cooked my retinas throuh my 24 hour contacts!

      Here is what I did: Buy something stiff but easy to cut like pink styrofoam insalation or foam board. Then cover it with fabric, all of it ending with a 'rosette' gathered in the center front. Here you can do most anything using staples or hot glue. I created 'twisted roses', twisting and pinning until I was happy then stapeling.

       Another half moon I simply used the pink foam insalation(buy this at your local dyi store, Lowes, Home Depot, etc. It's about $10.00 for a huge sheet, about the size of a door.) I made a pattern and simply cut a sleeve fastening it with Velcro. I used suede which bleached out in days on the street side, but who cares? The inside matches the rest of the drapes and they are lined. I guess you could line the half moon too, the pink stuff showed thru when I tried that so I just used the suede and frankly I didn't even notice, so why would anyone else!

      Now when I first moved in I bought 'temporary paper shades'. Very inexpensive, folded them in half, the whole folded blind; stapled the two halves as they met, just the two halves of the bottom blind, making a half moon! The reason I didn't keep these is that they were too light, opaque, they let lots of light thru.

      Hope this helps!

      Good Luck, CJ

      Good luck

      Thank you CTI for the great idea!  I hadn't thought of using anything else but fabric.  I appreciate your taking the time to post this to me.
