cloth, pins, thread, etc. used for sewing, or a shop or a department of a large store that sells these

There's a fabric store there that sells notions.

They sell fabric but as far as I know, they don't sell notions.

You can buy notions for patchwork and quilting.

They carry a good range of dressmaking notions.

I was looking online for some sewing notions.

You'll find zippers over in Notions.
