I send each bouce sheet ( or which ever brand I bought this month) thru twice... there is still plenty of "bounce/scent/de-cling left for a second load of laundry.
Lots of ppl use the sheets for foundation pieceing.. but warn it is highly flammable. So use caution, there.
I have planted a corner of a sheet in my garden to help keep critters/pests away.. ( just plant it enough so it does not blow away.. behind a tall plant and noone can see it sticking out) sees to work well for this... after a long season, I caught a momma robin hauling it off for her nesting.. LOL.... guess it was time to plant another sheet!
