HELP!!! I am looking for some type of lining fabric for KNITS. Does anyone know where I can find some? TIA ;D

Look in the inter facing area of Joann's. It is called knit tricot. There are two kinds, fusible and non fusible. It usually comes in white and black. I often use the fusible on the back of embroidery designs on T- shirts to prevent scratching. Also works well for inter facings for knits.

I use Fabric.com Here is the link to lining fabric. Hope this is helpful.

If it's for a skirt, any satiny material works.
