Changes I made to the original pattern: I used 8 ply (double knit) cotton, not 10 ply yarn (8 ply being the standard yarn width in Australia), and crocheted three motifs across, not four (as odd numbers look more balanced).
I made the starting chain using a 4.5 mm hook then used a 3.5 mm for the rest of the scarf. My starting chain was 12 ch plus a turning chain of 3. For the remainder of the turning chains I only did 2 ch, as it seemed to sit better.
