This free pattern was truly a delight to work with, the pleasure being with the outcome of the Hat. The pattern is written in simple terms. Just remember the space to dc in, is the space, not the eye of the dc, I did this at first and the spiral effect was not there, once I had over come this little hurdle it was on with the pattern and it was a breeze. It's written in US terms and some adjustments were made due to US yarn being different to AU yarn, I used a 5.00 and 6.00 hook, 12 ply yarn, I decreased the height and added a few simple decreases around the last few rows for a better fit with the Au yarn used. Here is the link to the free pattern.
Thanks to Rheatheylia for the pattern, she does have more free patterns with in her site.
