Mater-knit-y chic! Pregnant Katherine Heigl picks up a huge bundle of yarn while out on a coffee run in LA

She has a few months to kill before the arrival of her third child. 

And it looks like Katherine Heigl plans to spend some of her time knitting at home with her daughters while waiting for the big day.

The actress stepped out in Los Angeles on Tuesday and picked up some coffees to go as well as making sure to stock up on some chunky yarn for her creations.

By now it's become quite clear that the Valentino Rockstud collection is a celeb favorite. Katherine Heigl is the latest in a long line of A-list beauties to rock a design from the popular range.

She wore a pair of ballet flats by the Italian brand while out running errands and teamed them with an off-shoulder oversized top and cropped jeans.
