sorry if double post
this is my first knitting. im making a scarf. at first i make the casting on too long (i didnt count it) so it looks like this
dunno why it can become wider and a bit arched.
i though i can just stop the knit and make a new knit with same height then join them like this
so the question is what technique should i use to join them?
and if i want to combine with another color like this
would it be looks good?
thx before
