Lights all aglow

Just another thing that making me feel festive:  I love twinkly lights and Christmas trees.

Help!  I'm looking for some silk charmeuse - about a half yard or so.  Does anyone have a good internet source?  Or one that I can call and mail order?  Or any on hand that they would be willing to send me?   Any shade of blue, green, pink, or red would work.  Even black or gray.  I need it kind of quick - by Monday at the latest.  I'd be happy to do a swap or pay.  Thanks.
