There's a very nice pineapple one on this page for download at $2.50: http://www.crochetmemories.com/patterns/runnermenu.php

And a snowman one here for under $2: http://www.hassdesign.com/FiletCrochetDesigns/IP/HolidayPatterns/

I'll check tonight to see what I have.

I found one in my stash. Send me an email with "mantle" in the subject and I'll get it to you.

you could also check Crochet Pattern Central - look at the table runners as a place to start - they may have some you like and you could adjust the size
