I prefer patterns that are complete from jumpstreet!
I'd rather measure the person (bust/chest; back waist length; arm length; hip) and then choose the size that best suits the person...and then make adjustments for shorter (or longer) arms, etc.
I also prefer knitting from the hem to the neck (called bottom up)...and I prefer knitting all the pieces separately with the eventual seaming to follow. I prefer to block the pieces individually FLAT before seaming. It's a better outcome.
Most patterns try to have the same result, however they get there: a garment that fits. I've used both and hybrids of both, and so long as they all result in a garment that fits, I don't really much care -- for me it's sort of like getting to the same destination by a different street.
OTN: Eyelet Chemise in Handmaiden Sea Silk (colorway: Midnight). Still. And a purple Donegal Tweed set of fingerless mitts, to try out my new Hiya Hiya interchangeable needles.
Latest FO: A shrug for an Anthropologie swap in beautiful Casbah sock yarn, in Cedar, a dark green semi-solid, my own pattern. Also a quick Noro Silk Garden neckwarmer for my friend Aideen, in a vine lace pattern.
I like to measure and make sure the pattern with adjustments will fit the intended person. It is kind of like sewing you have to adjust for the person you are making it for. Some like a loose fit and others don't and I adjust for the preferences of the person.
