I tend to look at lots and lots of craft sites and the ideas and the inspirations are pretty much endless. It also occurs to me quite regularly, that if you find a craft that you like no matter what its original purpose, you can usually adapt it and reinvent it with a Jewish twist or theme. Here is a round-up of thanksgiving crafts, most of which will look quite lovely on the shabbos table. http://www.thecraftycrow.net/2010/11/thanksgiving_table_crafts.html
Creative Jewish Mom has more creative and jewish crafts for Chanukah too.
