Which Needles for Baby Blanket

Hi,
I am a new knitter. I want to make a baby blanket, but kind that even long needles are not allowing me to cast on enough stitches. Do I need circulars and how does that work?

thanks,
Dawn

You can, and should, use long circulars to knit wide things. You knit back and forth as you would with straight needles. The only difference is that the two needles are connected. No special tricks.

Thanks. Will buy some circulars tomorrow.
