  5. Hi. I'm fairly new to sewing and I thought i'd give this a go. I'm a bit confused as to how you did the placket. Is there anywhere I can get more detailed instructions?
    Thank you for the pattern.


    2. Where does the fabric for the neckband come from?

    3. I bought it here: You could also use jersey/ interlock fabric instead.

    1. Step 19: Take your ribbing fabric and cut it about 4,5 cm (1.8 in) wide (fabric length).

      So probably 25 cm will be enough.

  7. Well done, thanks from Canada!
