Cool - I have used Tissue paper doing this, but not dryer sheets...
i also discovered using baby wipes and reinker make an awesome background too when dried... I was re-inking and piecing together a my little pony b.d. card out of mulberry and wiped my brush (& fingers) on a babywipe and when it dryed it made a really cool background....
some of the best creations are created from not trying!! Like I always tell my classes, "there are no mistakes, that's what embellishments are for!"
