A little luxury

I suddenly realised that by doing this research on stated vs. actual yarn weight for my sock yarns meant that I'm going to have to sort of come clean on my sock yarn stash. * I also realised that many knitters considered speaking of their stash in numerical terms as being somewhat vulgar...a bit like showing off a Chippendale table and then telling 'all and sundry', how much it was recently valued for.

I weighed these issues of heart and head and decided to let head win. My natural curiosity about which companies were skating on the edge of acceptable skein weight and which ones were not was just too strong.

As I have recently tested my scale against one in the post office, I know that my scale is roughly accurate. Some skeins are above the stated weight, some are below. I converted all the ounces to grams so that there is a consistent measurement. For the US yarn companies, that still labelled in ounces, I converted the measures to grams.

I've also adjusted for label weight and included a 2g adjustment, so that basically means +/- 2g on the stated weight is a reasonable margin of error for the manufacturer to adjust for humidity, shrinkage, latitude on earth of where the yarn is milled and monthly gravitational pull of the moon ;-).

Again, I must note that I did not have 30 skeins of any one brand and that basically means that I don't have a valid sample size for any single company. I do have a valid sample size if we are considering sock yarns as a whole. Today's post is about the luxury brands. For a yarn to be considered a luxury brand, it has to retail at £9.75 or more for 100g. That meant that I had to exclude Tess's Designer Yarns from the luxury grouping, eventhough I thought it every bit as good as the Lorna's Laces.


The luxury brands

On the whole, they came out really good. You pay a bit more, but you are far less likely to get an undersize skein. Using a +/-2g margin of error, of the 49 skeins that I weighed,






    3 skeins came in slightly underweight

    26 came in at the stated weight +/- 2g

    20 came in over the stated weight

Colinette, CTH, Mt Colors, Schaefer's and Fleece Artist, all came in at or over the stated weight, even without the 2g adjustment.

Koigu and Lorna's Laces all came in roughly at, or slightly under the stated weight.

Although all skeins came in at the stated weight with the error margin applied, I didn't actually weigh enough of the Posh Yarn, Lisa Souza or Piece of Beauty to be able to draw any conclusions.

Mmmm... luxury sock yarn. I'm experiencing stash envy. Although if I had it, I probably would be too stresse out about finding a place to store it, and wouldn't enjoy it.

Polly, thank you *so* much for all your hard work. I have a skein of the Lana Grosse Boot Stretch in my stash. I'll weigh it, if I can, and get back to you.
I love that 'planning for your retirement' angle. I'll have to use that the next time I want extra money for yarn!

My question now is, how many yards (of average fingering/sock weight yarn) are there in three grams?? Math makes my head hurt...

Posted by: Adrienne at November 12, 2007 07:16 PM

Your findings in sock yarn weight are really interesting -- and they agree with my less scientific findings. I am, of course, weighing all my socks yarns from now on to check actual weight.

Wouldn't it be cool to have an online database where we could all enter our findings? Yes I know I need to get out more. ;-)

I hope you didn't tell your sock yarns about the helicopter / Scilly Islands story - If you did, they were probably getting all excited that their public weigh-in was going to result in a fun trip!

Posted by: meg at November 11, 2007 09:31 PM

Well, this gives me a reason to buy some of that Fleece Artist, doesn't it? I mean, what a bargain, 17 grams extra!

Posted by: Mary de B at November 11, 2007 03:30 PM

Oh Polly - I can't say a thing about your stash having spent most of yesterday re-organising mine, I am pretty much matching you skein for skein (tho' mine's not all sock yarn !)

I've always thought that yarn stashing is as important as saving for your retirement, so that when the time comes when you can't afford all of life's little luxuries, you have a private supply of luxuries waiting to be raided :-)
I have to say, though, you've been doing a better job of planning for your retirement than I have!

Posted by: Helen at November 11, 2007 08:37 AM

I love that you graphed it with variances and everything. Such a math geek, it's too funny! :-)
No judging on the size of sock yarn stash. I mentioned the number of my skeins of sock yarn and you pooh-poohed my stash as paltry or rather, baby stash. I'm good with that too!

Posted by: Wanda at November 11, 2007 06:19 AM

No chastisement here -- just envy! I am growing my sockyarn stash bit by bit, though. Thanks for the information of yardage/weight; it will be good to keep in mind at the LYS!

Posted by: Em at November 11, 2007 04:57 AM

That is so interesting. I am ready to go and weigh all my yarn, sock or not. Of course, that might take a couple of weeks.

Posted by: Monica at November 11, 2007 04:25 AM

Dude, my sock yarn stash is in the TRIPLE digits (and I'm NOT disclosinf which digits!) so don't worry about yours - no chastisement here! :)

Posted by: Debi at November 11, 2007 01:19 AM

Oh My Golly! No chastisement, just wonder and awe at your sock stash. I'd love to play in your stash, or just look at pictures. So apart from the wight issue, which are your favorites?

Posted by: kelley at November 10, 2007 10:15 PM

That's very, very informative and interesting. Thank you. I'd never make a judgemental comment on anyone else's stash but I'm of the, firmly held, opinion that sock yarn doesn't count anyway. Have you got a 'scientific' opinion on whether speed knittting increases the chances of a marginal amount of yarn being sufficient?

Posted by: Kirstie at November 10, 2007 09:09 PM

Okay, let me do that again. Bad stats major. I forgot to be dividing by root 49 in my confidence interval. It's really concluding with 95% confidence that the true mean difference is 3.7959 +/- 1.589 or (2.2069, 5.3849) and we conclude that the mean difference is in fact above 2. That makes more sense. *phew* Ignore my last comment :)

Posted by: Jenna at November 10, 2007 09:00 PM

If you'd like a wee bit of stats applied to that, using a 95% confidence interval we get an average difference of 3.7959 with a standard deviation of 5.6752. So throw that together, assuming it's normally distributed because n>40, and we can claim with 95% confidence that the true mean difference is 3.7959 +/- 11.1233 or that it's in the interval (-7.3274, 14.9189). So we can't conclude (from a statistical stand point) that the difference is actually anything other than zero as it's in our confidence interval. Sample size is still coming back to cause trouble because there's such a large variance (not variance in the sense you used it though). I'm still surprised at the huge range even if stats doesn't really work in our favour. 17g's over is a lot. Though it's to the advantage of knitters, you really wonder how much money the companies that regularly "over fill" the hanks are losing on it...

[in a daze] I love maths ...

Posted by: AmyP at November 10, 2007 07:10 PM

I don't have a leg to stand on, I can safely say that mine's bigger than yours and I don't include the vacuum pack of koigu as sock yarn!

Posted by: dawn at November 10, 2007 06:27 PM

You sorely tempt me to go home and weigh all my yarn!!! Maybe this will spread like the wind through the blogs, so that we might actually get some statistically valid conclusions ;-)

Posted by: Karen S at November 10, 2007 05:54 PM

Polly (and others), I'm "weighing in" today regarding yesterday's post on a "largish" project using singles yarn. It would be a very good idea to make an oversize gauge swatch. Sometimes, if the singles has any "overtwist" at all, the knitted item may bias. Also, it would be a good idea to hand wash the sample and lay flat to dry (don't block), just to make sure the "bias" doesn't appear after washing. Actually "singles" yarn can be fun if you can anticipate "bias" in your design!

Posted by: Bobbi at November 10, 2007 05:47 PM

Hey, you just have a lifetime of socks for the future. I see no problem with that! You are just a very careful person!

Posted by: Lynn at November 10, 2007 04:00 PM

Interesting!

Posted by: Maud at November 10, 2007 03:05 PM

That's actually very interesting. Thanks.
This should help in the cases were I'm knitting to the very last little bit of a skein and fear running out early.

And your yarn stash look so reasonable :)
