Cotton interlock is a wonderful knit fabric. It is extremely soft, very warm, and a little stretchy, perfect for baby garments. It is warmer than cotton jersey or rib knit because it is a double knit construction, making it thicker and heavier than a single knit.
Advantages of Cotton:
Natural fibers free of chemicals
Breathable – Great option for hot weather
Hypoallergenic and does not irritate skin
