Before you go: “How many ways are there to make a split ring?” I will answer you: “With 2 shuttles there is 1 way and with 1 shuttle there is 1 way to make a split ring.”
Now before you get confuse, the only different here will be the amount of double stitch made. SR: 5ds-5ds-5ds/6ds (A). See the different in how the written pattern. 5+5+5=15 not 6, that means the 2 sides are not the same. That is what makes this split ring different. That and the direction the stitches are facing (B).
