what do I DO with it?? (pipers' plaid)

[xman]

I would not alter the item. It is an antique pipers plaid. It should remain one. Perhaps it came to your Great-Grampy Bruce as a bequeathed item in a will from a dear friend. You wouldn't want to be responsible for cutting it up and find out later it was something very special, even more-so than I suggest perhaps.

My first thought is that you could easily use it as a laird's plaid if you like since you wear the same tartan.
At 10 feet it would make a nice draping somewhere, but be careful not to let it fade in the sunlight.
