Bitty baby booties -- free pattern that took blogger 30 mins. to knit (see notes about how she knit them backwards and sewed them inside out, which hid the seams and made the shape more rounded than original).
This is my Baby Pull On Boots knitting pattern. These booties are really quick and easy to make. The knitting pattern provides full instructions with photos to help you with the simple makeup. They use so little yarn they are a great way of using up leftovers.
