Okay, I've read all the post but as a "newbie" I'm confused as the prupose of doing this. Is this always done when making a quilt or is this a substitute for batting? I hope someone can answer this as I'm still learning the basics. Thanks!

You cannot sew assorted scraps (often cut on the bias) without a foundation. The dryer sheets are a cheap and easy foundation for scraps. They are not used in regular quilting where the quilt "sandwich" is made of the pieced top, batting and backing. You can make "crumbs" for scrap quilts by sewing scraps together but you must watch the grain and sew straight seams only.

Thanks Limey.......so if I'm understanding this correctly, the "scraps" need to be stabilized so the block doesn't get wonky? Thanks :)

Correct!

That is the coolest idea. I am going to start saving dryer sheets. I have never done a foundation quilt but I'm going to try now. Thanks for sharng.

This is a wonderful idea!

Great tip about using tumble drier sheets for foundation piecing.
Will start saving right away.

I would call around or check the internet.
I belong to a machine embroidery group and the guy who rights the manuals for the machine said not to use dryer sheets. There are chemicals on them that can build up on our machines.
He also stated that depending on the brand, some cause an oil like stain on the fabric, that does not come out.
Best to check.

Surely there is a difference between used and non-used sheets. And I can't imagine that anyone wd use them for embroidery.

This so cool. Would work for making postcards too. Thanks for sharing
