Border on my baby bibs

Hello,
I am new to knitting and trying a bib for my infant. I am following this link


and finished almost except border. I am struck at “Edging and Ties” part in the link.
I never used cirucular needle before. Can i do that border using straight needles? And if so please let me know how to pick the stitches into the needle? And i would appreciate if anyone can explain the step by step procedure to complete the border.

Thanks

You’ll need to use circulars to pick up sts around the edge of it, there’s a video that shows how to on the Advanced Techniques page near the bottom. Pick up the sts along the neckline, knit 3 rows and bind off. Then CO 50 sts and begin picking up sts around the other 3 edges and cast on 50 more sts for the other tie. Knit 3 rows over all these sts and bind off.
