Matching stripes.

 Thank you for your kind comments, Maureen.  

I was regarding the striped cardigan as easy knitting.  Here's the pattern:

I decided not to use the same sequence of colours, because I did not like how the cream divided it into blocks. When I was buying the yarn another customer commented that she had knitted the same pattern, but had felt the need to sort out the stripes at the sleeve head so they matched those on the body.  This is the sort of thing you hope the designer would have sorted out for you. Sadly, I did not ask how it had been done.

So I started knitting a sleeve and then realised that it would not happen automatically: the only way was to start at the sleeve-head and reverse the shaping.  I cast on 10 stitches and knitted the first stripe, increasing instead of decreasing.  Hmmm... I knitted several stripes before realising that would not work.  So then I tacked the shoulder seam together and it came to me that the cast on row would cover the first whole stripe on the body, so the first full stripe of the sleeve-head needed to be the second stripe of the body. 

 

Reversing the shaping was relatively easy once I got past this point, although working out the rate of decrease down the sleeve was a puzzle.  Perhaps this is why the designer decided not to match the stripes?
