How much wool is needed?

[KnittingQuery]

I am knitting a baby blanket, 103 stitches on 9mm needles, knitted in seed stitch.

I have chunky wool in 100g balls (Women's Institute soft & chunky).

Can somebody give me a (rough) idea please as to how much wool it will take? 🧶🙂

Thanks!

Can you give us a rough idea how long you’re aiming for ?

I would expect about 300-400g would be enough, if you have some left when the blanket is big enough you could make a little hat or something. (Based on having a baby blanket on the go which is 350g of DK yarn).

I asked ChatGPT, and this is what is came up with……

What does the pattern say?

You probably can’t see the results of this this Ravelry search for baby blankets knitted wholly in WI soft and chunky.

If you could you would see that people have taken between 3.5 and 10 100g skeins, which I appreciate is no help. The 3.5 one looks quite short but fine for in a baby buggy, has a seed stitch border and stocking stitch centre. I don’t own the patterns so I can’t tell how many stitches they used.

I suppose the answer is to guess, and knit until you run out of yarn.

Anyone else trying to help, the yarn is 70% acrylic, 30% merino, 110m per 100g.

Thanks everyone. I only have 300gms and I am not using a pattern, so will just knit until it runs out! 🙂

Could purchase a contrast colour to eke it out, I suppose. 🤔

I’d suggest knitting until you've used up one skein. That will tell you if the blanket will be long enough with 3 skeins. If not, one-skein blocks would look good, eg A B A B A with 2 more skeins of B.

Yeah @Octoberaddsagale I think that's what I'll do, thanks. 🙂

Can I ask, what search terms you used for the WI yarn baby blanket on Ravelry? I joined the site but didn't really find any WI yarn blankets. 🤔

I searched for the yarn first.

Then:
Projects
Advanced search
Then I filtered using: Finished, Knitting, Home (under pattern category), Blanket, Baby Blanket.

There may be a way to omit projects using other yarns in addition to the one you’re interested in, but I don’t know how.
I tried searching for Number of colours: 1, but that only gave me 2 results.

If there are lots of projects and you’re mostly interested in the total length used you can just look at yardage. Use a similar method if you want to only see those using your needle size, and gauge/ tension.

@Octoberaddsagale Meant to come back & say thanks. 🙂

Knit the blanket diagonally - start with one stitch, then increase at the beginning of every row. Once you’ve used half the yarn, start decreasing back to one stitch.

@maximist never heard of this method. Sounds good though, will try next time I'm knitting one, thanks. 🙂

I use a similar method to @maximist : this gives a slightly lacy edging. There is a school of thought that says baby blankets shouldn’t have (deliberate or accidental) holes in, though, especially if knitted in acrylic.

I cast on 3 stitches, then every row until you’ve used half the yarn is
Knit 1, yarn over, knit to the end. (Increase 1 stitch every row)

Just before half way do 2 rows of
Knit 1, yarn over, knit 2 together, knit to end (Increase 1, decrease 1, no change overall)

After halfway, every row is
Knit 1, yarn over, slip 1, knit 2 together, pass slipped stitch over, knit to end. (Increase 1 decrease 2 = decrease 1 every row)
