Are there other uses for worn out, torn. Queen size, fitted sheets?

You can donate to a quilting group that uses old sheets as quilt backing for charity projects. Check local churches

I make pillow cases for my dogs bed. easier to wash than the fluffy bed.

I used my old sheets as curtain linings, drop cloths, for toting leaves and yard debris to the compost pile. I like the fitted sheets for toting because I can position it so that it helps keep stuff in as I pull it across the yard!

you can use it for lining blinds, make stuffed toys, pillows, sunshade(sail type)

If it is cotton, you could make them into cleaning cloths, dusting cloths. If it is one that you really liked, you could easily make them into pillow cases, even use them as background on corkboards, pictures, etc. You could even use them for sewing clothes if you want, even doll clothes. I hope this gets more ideas flowing for you.

I use them as a box spring cover.
