Lies, Damn Lies
One of the difficulties with working with vintage patterns is working out what materials one should use given the original pattern was written for something that is no longer produced and about which it is not easy to find information. Most of the vintage patterns I have specify a weight for the amount of yarn required for a project. I learnt long ago that these specifications are incredibly unreliable.
I came across a little pattern the other day which proudly announced itself to be a “half-ounce scarf”. When finished it would measure 36 by 7½ inches. I was thoroughly skeptical and because it’s a little project I decided to do an experiment.
The original pattern calls for “Copley’s Cobweb” wool sold by Messrs. Bourne and Hollingsworth of Oxford Street, London. I figured that both Mr Bourne and Mr Hollingsworth are probably far too busy being dead for me to bother them about “Copley’s Cobweb” and if not, they probably wouldn’t honor the advertised price of just over a shilling per half-ounce skein anyway. I searched my stash for something that might make a suitable substitution. I found almost a full ounce of some fine baby wool, wound it into a skein (taking note of how many metres it contained), threw it in the dye pot to make it a little more interesting a colour then began to knit (well I let it dry first, but you get the picture).
Before long I knew that I wasn’t going to get a 36 inch scarf from the yarn I had. I knit up everything I had and measured the result: about 12 inches, not even close to half-way on almost twice the weight of wool specified. Granted I wasn’t using a proper lace-weight yarn (but it wasn’t that far off), but I now knew it took 95m of yarn to get to that point, so to complete the scarf I’d need about 285m. Off to the Internet to see if indeed anyone produces lace-weight yarn that weighs just half and ounce per 285m. After a rigorous ten-minute investigation I couldn’t find anything that came close, the best I could do was about 155m per half-ounce. [Edit: If I'd looked up "cobweb" yarn I would have come closer (about 195m per half-ounce). You can get the right yardage for the weight with a gossamer yarn but the pattern is knit on 5mm needles. Hardly an appealing combination to me and not what the accompanying picture looks like either. Maybe I'm missing something - let me know.]
So, either wool was astonishingly lighter than today’s products or many pattern writers were “overly optimistic” about the abilities of the wool they specified. Either way, don’t trust those weight specifications! I find that through experience you get a “feel” for how much yarn you need for a type of project. And if you don’t have that feel then find a modern pattern of similar type (e.g. compare apples with apples not knee length cardies with waist length jumpers) that has a yarn you can find the yardage of - use that as an estimate (and it never hurts to have a little extra for security).

The cobweb weight yarns of yesteryear were much lighter than those of today. They have to be
I used a half ounce of merino acrylic cobweb and got an entire 10″
so we either are doing something really wrong, or the yarns are very different.

Maybe we should join our two efforts - that gives us 22″, only another 14 needed!
It may be the spin in modern yarns - perhaps a firmer twist is used today making denser yarns?

Hello,
I just found vintagepurls through the free knitting pattern site and wanted to write and tell you what a great idea this is.
I love vintage patterns, clothes, fabric, etc…and this is a wonderful addition to my internet references.
thanks for all the hard work, I’ll keep an eye on what you’re up to,

I have just finished the front of the Ladie’s bobble jumper from your free patterns section.I shall be wearing it in October at a 1940’s re-enactment weekend.
It has given me a reason to get up in the mornings since finishing work due to ill health!
I am a vintage knitting addict and would like to thank you for allowing me to use your patterns and your wonderfull website.
I collect 1930’s/1940’s patterns myself and have been lucky enough to obtain some vintage wool to complete them.
Thankyou once again.

Kate, you’ve made my day! You will look fantastic in October (I’d love to see a photo). Best wishes.

[...] pattern reckons 2oz (about 60g) is all you need but that’s laughable (vintage patterns lie). I’ve got two balls of Big Baby, one is for security (these are 100g balls so that’s [...]

Hi,
The yarn shop that I work at has a book where you can look up any kind of yarn to an idea of the fiber content, weight, needle size, etc.
Maybe your’s has the same book.

Thanks Beth. Is this a published book or something information the shop has collated over the years?

Update on Ladie’s Bobble Jumper.
It has taken a while but the jumper is ready to sew up and French knot!
Good job really as I need it next Month!
It has taken me so long to do because of holiday’s etc.
I found the sleeves a bit confusing as they were too tight and so I worked 2 sleeve’s for each arm and sewed them together.
