This scarf is worked flat. After completing the main body of
the scarf, you work a second lace border and graft it to the
body. This means that the two borders will be the same. To get
a good colour match where the second lace border is grafted to
the scarf, pause after you have worked the first lace border and
weigh the piece (put it on some waste yarn so you don’t weigh
your needles!) Before working the second lace border, wind off
a small ball of yarn which weighs approximately the same as the
first border (allow a little extra). If you work the border from this
small ball, you should find the top of your border is roughly
the same colour as the end of your scarf. The stitch patterns can be
worked either from charts or written instructions, whichever you prefer.
