Knitting newbie - straight needles worth it?
I just started knitting a couple months ago and am just about to finish my first project (a simple pair of fingerless mitts that I can't actually use until Winter, yay!). Trying to be cost effective, the first few needles I bought were one set of small DPNs and a few different sizes of interchangable circular needles. These have worked fine so far but I want to get a few more sets of needles, particularly in other materials to see if I like something else better (right now I'm using harmony wood needles). I like the looks of some of the straight needles I've found but I'm not sure there's much point to them if I already have circulars and a few DPNs. Are there any advantages to straight needles compared to circulars or long DPNs, where you can knit both straight and in the round, other than just looking pretty and possibly costing a dollar or two less?
