The booties are a tiny version of Pamela Wynn's Elf Slippers. You can see other, larger shoes I have knit from this pattern here, here, and here. I knit these booties on smaller needles and did not felt them.
The sweater was knit from the Basic Seamless Crewneck Cardigan pattern in The Complete Book of Raglan Sweaters by Leisure Arts.
I think my new grandbaby will be pretty cute sporting this look next winter.
