Want to use lace covered window panes w/out blocking light for privacy

I have used 2 different methods in 2 different bathrooms to get privacy windows. The first bathroom I use a product called Galaxy Glass. I had seen the idea online but I took it up a notch by adding a non-adhesive, removable wall décor from aliexpress.com between the layers of clear Galaxy Glass. The product is sort of like kids glue in appearance. I applied it with 3 fingers, making circle motions all over the glass and on top of the clings. I did 3 coats and let it dry in between each one. The look was pretty good but I wanted more privacy. I had gotten the clear Galaxy Glass at Amazon - 2 large bottles ( 4 oz. each I think). How much you need will depend on your window. I couldn't find frosted Galaxy Glass on Amazon so I started calling the local craft stores. I found 2 smaller bottles at Hobby Lobby. I applied that to the window and now it really has privacy. Here's the link to the window I did. http://www.hometalk.com/diy/decorate/rooms/yikes-i-want-a-privacy-window-in-my-bathroom-29199882

If you want to incorporate lace into your window you could put the lace between the layers of Galaxy Glass or use it as a side curtain (like I used the red) to incorporate it into your décor.

The second bathroom window is still waiting to be done, but we're using privacy window cling. You might find these at Lowes or Home Depot, but again I turned to Amazon and also did an internet search because there are so many choices. We've used window cling before and have been very pleased with the results. It's easy to put on. Cut your piece of cling a little bigger than your window pane. Clean the pane then spray it with water. Put the cling on the window then spray the top surface with water. Start at the top and work down the sides, one at a time. Use a credit card or a squeegee to smooth out any bubbles. If you get a stubborn one, prick it with a pin then smooth the cling around it. It will not show. Once you have the top and the side done, smooth on the bottom. Keep smoothing until there are now bubbles. We then used a straight edge to trim the sides and the bottom. (Be sure to use a new blade) Wipe it all down and you're done. If you have trouble with a lot of bubbles or wrinkles (we did not) simply take a deep breath, take a break, and start over again. Don't lose your patience because it will smooth out. Like I said, we didn't have a problem, but I've read of people who have. I truly believe it's from trying to do it to fast or not using the sprayed water on the window and on the cling. BTW, we put some towels on the floor below the window, just in case there was a lot of water. (There wasn't.)

I wish you the best on the project. Be sure to take pictures as you go along so you can post it for the rest of us to enjoy.

you can use the old fashioned liquid laundry starch. Not the spray stuff. Cut the lace to fit the glass, wet with the starch....wring it out a bit and put it in your window, let dry. If you are talking curtains made of lace.. that's a different story...

Window film!

they're all right - window film is easy to get, thin machine lace can be adhered to the window with starch (not so good in a damp bathroom, better the film) or you can use Gallery Glass paint (try sponging it over a stencil, or actual lace taped in place)
