Can anyone point me in the direction of some cute knitting patterns (basic cross stitch works too) for some Christmassy designs for my husband's aunt to put on Christmas stockings for the new twins in the family?

I've searched the internet and found two. But I don't have any idea of places to look online.

Basically looking for santa, snowman, etc.

I'll share one I found:
Billy Bear's Storybook Cross Stitch & Knitting Patterns (http://www.billybear4kids.com/holidays/christmas/xs-santa.htm)

Knitting Pattern Central - Free Christmas Knitting Pattern Link Directory (http://www.knittingpatterncentral.com/directory/christmas.php)
Home page has free patterns for just about everything knit, too.

She also has free patterns for other crafts.

Poke around, and have fun! HTH :D
