I did the pattern for it, but I whipped it out in a bit of a hurry so it isn't really up to snuff. The central ring is 3-3-3-3 with a split ring of 5-5 into the first row. All of the other rings are 5-5 and the chains are 5-5 except for the chain at the outer point which is 7-7. The four rings on row 3 are all joined into the picot in the middle of the chain of row 2. Picots are usually shown as a single short line but in the interest of clarity I used a wee circle in place of the picot line.
Please let me know if it doesn't make sense or if you find a mistake.
