Using black velveteen....
 

Would using black velveteen as sashing be too heavy to use or not? I have lots & would like to use it up... Any suggestions helpful...

I would say "probably"....
How about using it as a backing?

It is directional - so that may or may not bother you. It's just something to be aware of.

You might want to put a small piece of it in water to see what it does. I've had some that had a lot of excess dye in it and turned the water black.

I would wash and dry it first - but I wash and dry everything washable before cutting it.

Mom made a red cotton velveteen sheath type dress for me when I was in high school. (Late 1950s)Loved that garment. It was washable - but we did not have a dryer back then.

If it survives the laundering well, I would consider using it.

I used brushed arnel ("they" used to make robes and housecoats out of it - it feels like a short-piled velvet) for a border and backing for a quilt for my grandsons. I used t-shirt knit for the binding.

Have you thought of using it say for a sweatshirt jacket instead. I'm thinking of trying my hand at making one for my 92yo mother as we can't seem to find a chocolate brown cardigan sweater her size. Thought why not make her a sweatshirt jacket using various browns I have in my stash. I think a black velveteen jacket would look wonderful if you have a mind to try it plus it would use up a bit of your stash I'd think.

I too would consider using it if it washes up ok. I'm envisioning it more as an accent though, like sashing or points of a star, for example. It may be too heavy for the main fabric? (Just my opinion)

I think velveteen would be great with a heavier denim.

I think it has a nap. Try a small sampler and see what you think

My sister made a turning 20 quilt a long time ago and used black velveteen as 1 1/2” wide sashing around each piece and the outside border. It was her very first quilt and I still have it. It is a lovely quilt. Weight - wise it is fine, she did have some trouble quilting the outside borders - but, it was her very first quilt- and she tried to quilt the borders with a machine decorative stitch. It turned out nice but caused her stress through the process.

Velvet & velveteen has to be pressed against a needle board. Even if it were light weight fabric it would be a job.
