craftgrrl | Need ideas, thanks to a friend for directing me to ask here

I have two front windows that currently sport old sheets...not very attractive to say the least.

Last winter the windows were replaced and the landlord had mini blinds that were in horrible shape that had to go because they attached to the old windows (as featured in the picture).

Don't mind the horrible decor and gross aquarium ,the aquarium is gone from there, I am broke so I can't really update that much.

Anyhow, those are the measurements I can deal with.

I did a little bit more measuring, the actual width of the window is 41 1/2" the actual length from the top of the window seat to the bottom of the rod is 56 1/2" and the rod is 4" in circumference.

I was thinking on crocheting up some coverings but not sure if that will look tacky. I no longer have a sewing machine so anything I do needs to be no-sew. I do have an iron though.

My main colors are beige with accents of marroon (burgandy), forest green and a deep navy and yes I am a Broncos fan. ;-)

Thoughts?

Edited to add: I have an extremely limited budget. :-)
