I think it probably took me a month.
One thing I found is that I really do have to hold my yarn a lot looser than I am used to as I tend to have to knit a needle size larger when knitting English style to hit gauge.
With my Continental I am pretty much bang on gauge with the recommended needle size.
But the whole 'feeding' of the yarn bit drove me bonkers.
So I simply cast on a number of "stuffie" blankets and knit off as much as I could a night. Stuffie Blankets are what my children use for their stuffed animals. Each stuffed toy requires a blanket... Naturally they must be knitted by Momma. I tried to pass off some machine serged fabric squares but they don't get used.
Anyhow. They are great for learning a new technique, cast on about 30 - 45 sts and just do whatever! Cast off when the blankie goes around the stuffie for whom it is designated!
I started by doing 1 blankie a night and ended after about 10. But I had finished two in that night so I figured I 'got' it.
Otherwise, I know what really taught me English knitting was making a large simple poncho knit in the round for my mother. The simple repetition is great and you don't have to put it down so once you are happy with your gauge you can knit until your bladder is a critical error stage... :teehee: This would be a great option to knitting blankies if your not in a position to have a use for these wonderful knitted items!
Best of Luck!
