This “Dizzy” square originally comes from stitch11.
Its original pattern is worked with 9 different colours in aran weight yarn on 6 mm hooks which results in a 12 inch / 30 cm square.
The project I’m working on requires DK on 4 mm and I only had 2 colours, so it requires a bit of tweaking. The square shown here follows the pattern below and measures 8 inch / 20 cm.
It’s also a US pattern so I’ve converted it into UK terminology.
If a larger square is required repeat round 11.
