A new favorite
Also great with cotton yarns.
I had a bit difficulties in finding the pattern so I have written the pattern / tutorial here. This is a combination of the patterns I found on the net:
START with the Magic Ring method (I use this) or ch4 and join with a slip stitch
ROUND 3 (Cluster stitches): Change color and join in the space between two puff stitches. Ch 1, dc4tog. Repeat 15 more times, join with a slip stitch. Fasten off.
dc4tog: In the space between two puffs, *yarn over hook, insert hook in the space between puffs, pull up a loop, yarn over hook, draw a loop through only the two first two loops on the hook.* Repeat *-* three more times inserting hook into the same space, yarn over and draw a loop through all the loops (there should be 5 loops) on the hook.
And you have a beautiful sunburst square!
