Ok so in my haste to knit something in the round - anything.
I went to the store and purchased 2 sets of circular needles.
both 29" one pair is a size 8 (US) the 2nd is a size 10(US)
Question is … can I knit a hat for adult male (with a big noggin) on either of these needles?
Do they need to be smaller than the finished product?
For example I just saw a pattern that called for 16" needles for a womans hat that is 20"
Do I have to go back to the craft store?
Those are way too long to knit a hat using the standard technique. You could try the Magic Loop technique but I think they’re really too short for that.
You need to have 16" for hats, or two circs of the same size and use the two circs method, or one of a longer length and use Magic Loop.
Clear as mud? :teehee:
Not a bad thing really… 
so then what would you use the 29" needles for?
Could you do the body of a sweater?
Wait - You can do flat knitting with circular needles too?
So I could use the 29" needles to do a blanket?
I will be dangerous when I figure out how to knit.
Yes, I use circs for everything, hats, scarves, sweaters and 29" is a good length. Look at the video under Advanced techniques, Small diameter knitting to learn how Magic Loop works. Then find yourself a hat pattern and go for it.
Yes, circular needles are great for flat knitting too and the 29 incher will work for a lot of things. Very nice needle to have.
