I've finished a sweater and now need to sew it up. The yarn is super thick and I used US 15 needles to knit. My question is: What type and what sizes of needles do I generally need to finish projects? Are bent needles better? I have been working with a variety of yarn thicknesses so I'm looking to get a few needles to finish jobs. Thanks!

I like the Chibi needles.

Chibi seems to have both types, bent and straight. I've only used the straight yarn needles, but I've heard the bent ones are awesome.

I've ordered the Chibi!
