Yes , the blanket from squares is good , my little nan ( gt gran , only 4' 11") used to do that . Hundreds of squares made from wool she got from old jumpers that nan , her daughter , got from jumble sales .
Problem i would have is there are no jumble sales round here , charity shops to far away and too dear .
Aiso i don't want acrylic or poly whatever . I don't mind using it to practice with , even knit , undo and re-knit .
I can have sheep fleeces , but i will be in a 15' caravan with 3 spaniels , so no room for anything like a spinning wheel , not even a spindle , needles i can squeeze in . There is no rush for a jumper or anything else .
So if i made a jumper , i could keep it till i had real wool to use , then bin it , but a blanket made with acrylic or poly would be around for years , and i do want shot of plastic , man made fibres .
I wear cotton socks , cotton denim jeans and trousers , cotton undies , cotton or linen shirts and wax cotton coats . Acrylic and poly 100% has all gone , acrylic , poly cotton mixes go in the bin when they wear out , and get replaced by cotton , linen etc , all natural fibre .
This is the reason for me wanting to learn to knit , so i can provide all my own clothing , in conjunction with weaving home grown flax , wool etc .
I did this years ago , 30+ , but mum was alive then and knitted my jumpers etc , while i did the weaving , i also made my own leather too , got to start that again as well . I can get cow hides for free from local farmers , just need the salt , lime and containers to treat them in , the other stuff needed can be provided either by dog or chicken , and that is free and plentyful !
So the 'wool' will be what my aunt can get cheap on boot sales , i have no idea what it will be .
Even though i worked in knitting factory for 3 years , to me wool is just thick or thin ! I know , what a div !
