Donate the fabric locally to someone who can use it. You received it as a gift, so gift it to someone else. Freecycle is a great place to pass on items. If I kept all the fabric people gave me to "quilt" with, my house would be overflowing. I simply don't keep anything not 100% cotton.

hey dont count out the fake fur some people still make homemade teddy bears i found some fake fur and some type of sheepskin in my moms things and theyre good for making bears. crazy quilt with the more delacate stuff thats not real washable it can be framed after finishing and the textured stuff is good for alzheimer patients wheel chair quilts they like to feel things. hmmm did i miss anything ??? lol

Doll clothes and purses.

chenille scarves could be made with the rayon. I haven't made one yet, but I have a friend that has and they have a nice drape for a scarf.

I was just going to say that, but probably would not want to wash first, unless it is smelly or dirty.

The rayons can be used for quilted jackets and coats, if there's enough.

The police and social workers will gladly take clean teddy bears. When they take a child into custody they like to give them something of their own to hold. They go through a lot of teddy bears around here.

Inappropriate Fabrics
 

We get 1 or 2 bags donated by a local thrift store every week. The fabric we can't use, we donate to the American Legion. They use it to make pillows, dolls, stuffed animals, etc., that they then sell at the VA hospital as fundraisers. Some of the items they make go directly to the Vets in the hospital.

If rayon is pre-washed before it is made into anything the project won't shrink. I used to make cloths for my girls all the time. I washed the rayon in warm and dried in the dryer before cutting out then once it was made up it could be machine washed and dried. Clothes of rayon bought in the store are not pre washed before being made up, so they have to be dry cleaned. Raayon can have up to 10% shrinkage.

I'm one of those people who never prewashes her quilting cotton but I do prewash my rayon beofre sewing clothing. I probably learned this trick here on the board. With rayon, I sew a quick hem on the raw edges so they won't make a frayed mess in the washer or dryer. Then I fold the yardage in big 8 to 12 inch accordian folds and put a large safety pin in the selvage on one side. When I pull it out of the dryer, it's somewhat wrinly around the safety pin but otherwise ready to fold and store or cut and use instead of being in a 5 yard long twisted rayon rope mess. Also, last summer when I made some rayon batik tops, I starched the fabric before cutting it. The starch made it less slippery to work with and kept it from fraying quite as much as I handled it and washed out afterwards so it was still soft to wear. I love the feel of rayon for tops, dresses, and pus even if it does require a little more attention when sewing the seams. I've been toying with the idea of making a quilted (not pieced) rayon shawl.
So, yes, someone's junk is another's treasure. Lucky you!
