Spare ball(s) of wool

This is a bit of a long shot, but I’ve been knitting a small mat for a table and have run out of wool. Just one or two balls would finish the job. The yarn is Stylecraft Alpaca Tweed DK in Sage which has been discontinued and I wondered if anyone has any left over yarn I could buy.
Many thanks

Have you tried Ravelry? A yarn search can be narrowed down by color.

Even when the yarn is listed as “Not for Sale” it may be worth sending a message as that is the default and people often don’t bother to change it.
