Down in Soho, there is a place that sell really nice wool, tartan, tweed, etc. It is also very expensive. But further down the street is their outlet where they sell remnants. I found several 2-3 meter pieces of this heavy plaid and an almost 2 meter piece of greenish tweed that had "Woven in Scotland" woven into the selvage. I wanted to use that for my apron and selvage piece for a kilt.
I could sew enough of the plaid together, and hide the seams in the seats of the pleats to get my almost 9 meters. As long as I can keep finding the wool, i think these things might be an unhealthy addiction.
