Great ideas.
I always use rags for cleaning, and yes, they are good if you can overlock them.
I also use them for draining wet / fried food where I might otherwise use kitchen paper. I have a bucket and sling them in for regular boil washes.
I also make, depending on the fabric, handkerchiefs or make-up / cleaning pads.
I have also used at the lining / interlining for face coverings.
You say that you are not good at sewing, but should you want to try making clothes again, you can use old sheets for making toiles.
