i've used them as (doilies) sitting under a bouquet in a vase- in the center of a quilt-
they make wonderful aprons- in fact in our little sewing group one of the ladies brought us in a cute pattern for 1/2 aprons made out of them-
i've used them appliqued to blocks----the first time i cut one of my great grandma's hankies in half- it was very (tramatic!) but then it all turned out so great it was ok...after that first one i found it easy to start using them...they have also become parts of crazy quilt blocks-
if they are very thin you can add a lightweight stablizer-
