Thanks for the responses!
Yardstore a great idea, I was looking for an online source apologies that I wasn't clear on that.
Linen is used in the method I was taught; there might be a reason behind it, I'm assuming it is to prevent any possibility of the cotton material fraying off into the finish but I don't know.
The fella that taught me was very educated...he even sells the polishing materials online, however his prices weren't ideal for larger quantities of the polishing materials, more geared towards sale of high quality Shellac than the finishing materials (he has very nicely priced high quality (fresh de-waxed) Shellac.
All that said, I found the linen online through Amazon, didn't realize I just had to put in linen by the yard to get results---so I'm all set.
He (Vijay Velji) is a prominent figure in the Shellac industry, came out to a woodworking course I'm taking and did a demo which blew the entire class away. We were clapping enthusiastically after the demo.
You may have heard of him, he has been in fine woodworking magazine, on woodwhisper podcast etc.
Anyone doing Shellac, or interested in doing Shellac should give his website a look and buy a sample pack for testing; I don't think you will be disappointed if Shellac is what you are into for a project or two.
Here is his site if anyone is curious.
