An inexpensive way is to buy bed sheets and use as drapes. Will help block out some of the morning and afternoon sun, until you can purchase blinds. Painters drop cloth is also an easy and quick fix. Here are some ideas on Hometalk.

Sheer curtains may help with that problem, it did in our home. We put decor curtains on the side but only sheers in the middle for a single rod protection to let in light but not direct sunshine. HOpe this helps

1. Buy rice paper at an art store (a true art supply store, not a hobby store). It is reasonably priced. Cut ever so slightly smaller than window panes

and use gorilla tape (it comes in clear now) to attach. You can also use wax paper.

2. Buy canvas drop cloths at any big box store or hardware store. It can even be dyed, painted, stained. Pleat and nail in place over windows.

There is film you can cover your windows with that blocks damaging sun rays. Some types are just put against the glass and held by static cling, others have a sticky surface. Very easy to cut and install with a utility knife.

I had the same problem. I bought 3M film that filters our 85% of the damaging rays. I think they now make one even better in the 97% range. Made a huge difference blocking out glaring rays as well as the house temperature. You can buy the see-through tinted film and cut to fit the window. Application is amazingly simple by liberally spraying the film with a spray bottle filled with mostly water + a few drops of dish soap and using a squeegee to smoothe down the film. Or you can hire professionals, but the labor is pricey, so DIY. Not hard. There are also films that look like stained or cut glass you can buy at Home Depot or Lowes or online to apply the same way.

If you have any thrift stores near you, look for the kind of drapes that block heat. They are usually backed with rubber or are shiny like aluminum foil. Use an ordinary curtain rod and drape hooks to hold them up until you can figure out something permanent to do with it. It's the cheapest solution I know of besides nailing up a blanket or sheet to cover the window.

There is a film you can have put on by professionals that is guaranteed for life. Never needs washing so no ladder needed. A permanent fix. I have used it for high windows in two homes and wouldn’t use anything else. Prevents glare, UV fading but allows light through. You don’t even know it’s there!

To save money, you can buy the window film at Home Depot and install it yourself. It is easy to install. If you don't have a ladder tall enough, you can rent one while you are there picking up the window film! You can also order the film online, from places like eBay. Gila is the brand I've used, but 3M also makes a good one.

You need UV reflective window film, it comes in 4 colors.... https://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Dtools&field-keywords=UV+reflective+window+film&rh=n%3A228013%2Ck%3AUV+reflective+window+film

You will need a tall ladder, you just cut to size, spritz window with water and a drop of dish soap, place and a squeegee to apply

Have you thought about using voile curtains such as the ones used on French doors? They are not very expensive and can be found on line, especially under Brylane Home for reasonable prices starting at about $7.99 per panel. Curtains can be installed on tension rods and taken down for easy cleaning. Come fashionable colors or plain white and off-white. Lengths start at 35" (30 on some sites) and go as long as 72". Also try Amazon, Wayfair and Overstock.

I agree with Gvargo and have done this is our house. We have a living room with 8 large windows and a gLass sliding door. This room gets sun all day. I didn’t want our furniture get sun bleached. I used electrical conduit pipe as a rod because the wall are quite long. Here are two pics...I love the result. Hope this helps.

Perhaps if you look at my transom window project, it will give you some ideas. I did this on the West facing windows and could not be happier with the results. https://www.hometalk.com/diy/windows-doors/windows/transom-window-treatment-31574554

There are almost translucent shades available which let in the light but block the sun and the heat. You sometimes see them restaurants and they have a chain on the side for opening and closing if necessary.

Frost them. That would still let some light in but not so bright and glaring.
