Welcome to the Quilting Board!
Here in G.B. we were told not to use the sheets in our dryer because the cause damage to it, so it isn't an option for me, although i do use a stabiliser called stitch and tear easily, I love the tip about the labels - i will certainly be using that thanks.
I used them in dryer one time and I didn't do anything more with them and tryed them for app. and got powder residue from them was concerned about it wrecking my machine. Will try them again but will wash them. Thank you all for info
Dryer sheets have worked great for me, of course they already were in the dryer and were used.
