Are you guys saying that you don't use the dryer sheets a couple of times. I just throw them back in the dryer with the next load until they are soft. I add a new sheet with the new load and wind up with a bunch of used dryer sheets.
I press them before using for applique. Also, years ago, the dryer repair man said to wash your filter/screen because the softener builds up and can cause a fire. When you try to run water through the screen you can see where the softener is because the water will pool there. I scrub with an old brush.
