Circular Needles Vs. Double-Pointed

I’d like to knit a hat for my mom, but the circular needle I have is too long at 24", so I can’t join the round. I have a pair of double-pointed needles, and I think I can easily knit the hat on them, but I’m wondering if this would alter the gauge somehow, or mess up the pattern? Aren’t double-pointed needles and circular ones essentially the same, in that I can use them to achieve the same results? Sorry, but I’m a bit confused! Not to mention broke, which is why I’m hesitant to go out and buy another pair of circulars!

If the double pointed needles are the same size as the circ you should get the same results. A circular is essentially an infinite number of dpns joined together. Or, looking at it the other way, dpns are just a circle broken up into several sections. Either way, you’re knitting in the round.

Sure you could use dpns instead, though I use 24" ones for hats. I CO to another one, usually the next size up, and then join and knit the first round with the size I intend to use. The cuff is still too small, so I use a variation of ML - Modified Magic Loop - for a few more rows. I usually inc a few stitches, and then the 24" works fine until a few decs where I switch back to the MML till I have to use a real ML.

You can also knit it on 2 circs and the length doesn’t matter, though you wouldn’t want a real long one.
