Uiiiii a knitted sweater!!! What pattern did you use? I guess you are knitting it bottom up, that's a technique I still haven't tried. I am curious how it will come along. So far, the colours are lovely and the fuzzy yarn too.
If I must put the life stitches (for example of the sleeves, when I am knitting a sweater top down) on a something, I seldom use yarn, but mostly a spare cable with stoppers. It is later easier to use, because I do not have to transfer the stitches back on a cable - they are already on a cable and I only must remove the stoppers and screw/click the needles on.
Which needles do you use (I use Addi click)?
