Why yes, it really does. Seashell Sonata is a good example!
Here's Bailey's top. I made it for her last year. I knit it in the round with size 4mm needles. It was made from 2 balls of yarn (she was 6; I didn't really need to use a lot) and I only had to engineer the yarn a little bit at the one join.
This weekend, I started Soleil for DD #1. I was sure she'd LOVE the mix of khaki and blue. I got out my 2.5mms, and cast on. And I ended up with a lovely blend, and not a whole lot of splotchy-poo. Well, I screwed up my Soleil cast-on and twisted it. I discovered this about 1 1/2" in. Much swearing. I changed my mind and picked up Chicknits Ribby Tank. It's Soleil, with ribs. Frankly, I am in no shape to seriously figure out the math and all that mess. This eyepatch makes me stupid. (Ok, maybe it just reveals the stupidity....)
I cast on Ribby. I worked my obligatory bottom rib with 2.5s, then I switched sizes to 4mm very obediently when Bonnie said to switch. Pssht. Seashell started in with her old tricks. No prob, I thought, I'll just alternate balls of yarn every other round. So I labored up another 4".
This morning, I took a good look at what I was doing and thought !@#$?? Man, I sure am working hard for no good reason! So I switched BACK to the 2.5mms. It looks better, and it's less work. I am not gonna frog it. I am not going to do squat except pick the side that swirls better for the front. I am not going to call this "I screwed up"; this is called waist shaping.
That's my story and I am sticking to it.
