What I use leftover batting for..
 

My swifter mop it is a lot cheaper and does a lot better job than the store-bought ones

What a clever idea, thanks.

funny I may have to try that with those small pieces of batting - better than wasting them

Great idea! I use left-over backing and batting for my small/wall/doll/mini quilts too.

I pin a small piece of batting to my shirt and throw thread ends on it when sewing. Works great when I'm hand piecing or quilting.

I will have to try it. We have lots of hard wood floors

Are we talking about polyester batting or cotton, like warm and natural?

Good idea! I'm getting tired of going out of the house with a speckled look all down the front of me.

I also use my scraps of batting to clean the rails on my longarm

I use my clippings and small trimming pieces or those pieces too small for projects for the stuffing for dog beds for our local shelter. The dogs and yes, cats, don't mind lumpy they just like to be off the floor or the cage wire and these can be tossed in the washer if needed or just tossed out if too soiled.

This is our quilt service project and we have made dozens of them just from out scraps of batting or small fabric scraps.
