Well you can post the dilemma here with a lot of info and pictures of the space as it is. Often we post pics back to show what we are thinking so that should help. Other than that a good designer can help bring changes to life with story boards or even pics from projects they have done for a visual. I will say most men are not into visualizing decor . I usually just go ahead with waht i want and hubby just enjoys it .BTW post all that info her ein comments DO NOT start another post. I love that chndelier .

You have some spaces with unusual proportions and the furniture I see doesn't look like it will fit well in this space. Normally I don't suggest hiring a designer when people come here asking for help, but I think you need in person help in this space. Those curtains need to be custom as this isn't an off the shelf window size. The curtain rod should also be longer and any drapes need to be much fuller for that size window.

As far as making mood boards, I use MS Publisher.

As far as the husband ... do one room and ask him to trust your decisions/choices. Once we had visitors start coming in and complimenting my choices he stopped questioning them and was happy to take shared credit! This is what worked for me and the only time I get my DH involved now, is for buying seating. I narrow the choices down first by designs I like, and then we go test those out and he picks the most comfortable one for him.

This is the scale/volume you need to be visualizing for the drapes ...

Some here use Photoshop.

I just use Windows MS Paint and 'draw' out my ideas.

I clean up furnishing images using Remove.bg

However, it's best when you take photos of your rooms at the same standing height.

Your first photo is useless.

The diameter of your curtain rod needs to be at least 2 inches. You will need more than one curtain panel per side as well.

We just moved in to a new home. There is so much to do! I am full of ideas!

It's bigger than a bread box. Hire a designer and/or post room dimensions and what you're thinking on Houzz.....or....spend years trying it on your own.

I use Google slides to make mood boards. Easy and free. It has really helped me visualize and organize my ideas.

I tend to have a million projects going at one time and it can be so overwhelming. Pick one room and start there.
