As a former school teacher and preschool director, please ask the art teacher first. I know folks have big hearts and want to donate to schools and most of the time these donations are much appreciated but ask if the teacher can use your scrap donation. If they cannot use it the donation will end up in the trash or stuffed in a cupboard for years and that is not what you want.

You may ask around your area or local quilt guilds too if any one can use your wee bitty scraps. I know we have someone who makes dog bed outs of scraps of batting. Never even considered that until she mentioned it in class one evening. There may be a secret user of small scraps just an arm length away.

Call your local animal shelter. A bunch of us save all those "snippets" and batting scraps. Once a year get together to sew up pillows for the shelter.

I think it was a couple of years ago I read where someone took a bunch of threads, put them between 2 layers of water soluble stabilizer and just stitched in a crazy manner all over the threads to connect them. Then she dissolved the stabilizer and made a vest or something with it as right now I can't recall what it was but I don't see why you couldn't do the same thing with the small strings. Maybe use a fabric behind it to give it stability.

You could buy some of the clear plastic or glass ornaments available at craft stores and fill them with little tiny pieces. That's what I'm planning to do with my embroidery thread scraps. I figure it will make an appropriate ornament for a quilter/embroiderer.

I give my scraps to a school so the kids can make collages from them! The teacher is only to glad to accept them.

I've seen some quilters use them as stuffing for small items -like pin cushions. Just a thought.

If they are long enough, how about crocheting a bag? I have a pattern for a crochet (or knitting..I forget!) Christmas stocking. They also might be used for locker hooking a rug. I have piles for scrap quilting/leaders and enders/strips/ strings and finally they end up in the dog bed pile! My quilty friends bring me THEIR scraps (you might get as crazy as me and go thru THEIR scraps...some of that stuff is big enought to cut!) and once in awhile, I make dog beds. I think there have been upwards of 300 made from all scraps generated. My local shelter says that sometimes they give a bed to the new family. (I LOVE that part! http://bzyqltr.blogspot.com/search?q=locker+hooking

My niece is only eight and I give the snippets/thinner scraps to her. She's been practicing with her hand stitching at home. When she comes to my house, she'll bring her "stringies" as she likes to call them and see if she can match up to other pieces. She has resorted to using her little fingers as measurements. The strings that she thinks are too small she knots up and braids and has her mom press and makes coasters. Her pinky finger is about a 1/4" wide. She's very clever and uses that as her 1/4" seam allowance.

make potholders, placemats, Christmas gifts, purses, almost anything and Great for paper piecing .
this quilt is made from scraps .[ATTACH=CONFIG]444904[/ATTACH]

honestly, please consider stuffing something like a simple "pillowcase" shape for an animal shelter. concrete floors are cold on animals there who may have been rescued from even worse circumstances and just need a safe place to get warm.
