This is my Baby 3 Button Booties knitting pattern.
They are worked flat on 2.75 mm needles in any dk (8ply) yarn of your choice.
The knitting pattern provides full instructions for 4 sizes, XS (preemie and tiny baby), S (newborn-3 months), M (3-6 months) and L (6-9 months) with lots of step by step photos to help you with the makeup.
