Large Sizes Use How Much Yarn?

Hi all. I'm Jonna and I'm just now joining the CPH KAL. I have two questions relating to knitting the large size hoodie.
First, for the 52" size, the yarn requirements are almost 3,000 yards and this seems like a really large amount. On Knitting Daily, as an answer to someone in the comment section (which day?), Lisa Shroyer said, basically, you need that much yarn to cover us 'big' folks. But on other cardigans I've looked at in the larger sizes, the amount is closer to 2,000 yards. I could even see adding another 500 for the hood but.... so has anyone done these larger sizes and did you actually use the yardage the pattern suggests.
My second question is about the sleeves. I noticed a difference between sleeve shapes in the schematic and I was thinking about doing a 52" bottom but a 48" top. There seems to be more of a slope on the larger size and the difference in inches spanned along the top is double!
Anyway, I really appreciate any help anyone can give me before I start. But I'm so excited to get going that I may just buy the large amount of yarn and work out the sleeves later.

Blocking question

I am still in the process of knitting my CPH. I knit the back in a size 36 according to the pattern and I felt comfortable with how it looked, sizewise. However, as I worked on the right front, I worried that it looked too narrow and added a few stitches to both the center and side seam. Now it looks better. But now I'm worried about the back. Would it be ok to block the back before I do the seaming and the front band? If I did that, I think I could see more clearly if it fit.

I finished ages ago...

...But neglected to get pictures until very, very recently. I actually finished the knitting last spring/summer when it was impossible to wear, so didn't bother putting in a zipper until this fall.



Lately though I've been wearing this almost every day! I love it. Here are the specifics:

Size: 52" -- I made my own modifications based on other sizes, although it's great to see larger sizes available through Knitting Daily! There's a thread for my mods on Ravelry.
Yarn: Classic Elite Skye Tweed -- I want to say the color is "Grampian Purple"
Modifications: Besides size, I also did a zipper (obviously), short row shoulders (thanks to this KAL!), and made sure the sleeves were ample enough :)

I do wish I had made it a smidgen longer, but I hope it'll get longer when my baby bump gets smaller :)

Thanks for all the great advice and inspiration on this KAL!

Couldn't Resist the CPH

I bought Moda Dea Silk 'n Wool in Sangria for my Central Park Hoodie rendition. (It's a dark color & very difficult to capture in a photo. Sorry about that.)
I am combing the smallest size Back with the next size up Front to get the measurement I want and the majority of the sizing on the front side. This will accomodate my smaller frame with my larger than average cup size. I got the idea from my years of sewing experience alongside sweater attempts that resulted in "baggy in all the wrong places" finished products. I have 8" pictured here on the Back View. I'll knit it up to the 14" in order for the Fronts & Back pieces to match.
I decided obviously not to knit-in-the-round. I felt that this yarn was pretty hefty & my wrists are already sore from the weight of my Puff Sleeved Cardi. This yarn has a pretty sheen (my current obsession) and is very soft, yet it holds stitches crisply. I think that this will be a fast knit for me as it is an easily memorized pattern & pretty mindless. I am knitting away here.

D's CPH

After reading Lauren's post about knitting this body of the sweater in one piece, I thought this was an excellent idea - I also hate seaming.

I have made a few adjustments, eliminating a stitch at each edge for selvage, then adding an extra set of cables – which will be under the arms (where the seam should be).

I am knitting the hoodie in Medium size (40"), so I adjusted the pattern, so I have 10 stitches inbetween each set of cables.
