cardigan patterns (stitches)
Could you please help me to identify patterns (stitches) of Tilly Masterson's cardigan, size of knitting needles, and size of yarn from the picture at the link: http://bamfstyle.files.wordpress.com/2013/06/2013-06-08-01-42-25-pm.jpg
No. I can make educated guesses but without getting a better look at the garment, it would more very rough.
I would assume it is an 8 ply (double knitting) pattern, so it would be knitted on 4.00 mm (8 in English sizes), but as I said I am just guessing.
As for the stitch patterns, I can't see all of the cardigan so there may be other stitch patterns on the back, but on the front I can see a bobble panel and a couple of large cables. I could probably come up with something similar in my knitting stitch library, but without a basic aran pattern to work on it wouldn't do you any good.
I suggest that rather than trying to recreate this pattern you do a search for vintage aran patterns online. You might be able to find one (or even this one) from the same era.
Sorry I couldn't be of more help.
