I'm using a very thick wool for a School Days coat and it's so thick that a double layer needs to be squeezed and prodded to get it under the presser foot at all! It doesn't ravel, so I tried stitching down the seam allowances to hold them in place. I tried two different spacings and while the wider one (a line a little farther out from the seam line) looks better, neither looks all that great. It's a little hard to even see what's happening as the material is so fluffy. Imagine a cross between cord and melton -- no pile in the sense of being directional, but puffy and kind of striped. Have I hit a thousand words yet? Haha. It's too dark to take a decent photo but I'll post one in the morning.
Any suggestions for handling this stuff?
