This pattern isn’t available any more, but I was able to sort of reconstruct it from the other project photos and by looking at the Jacob’s Ladder Round Baby Blanket pattern from Bev’s Country Cottage.
If I make this again, I might think about using 12 segments instead of 13 but also making more rounds, as this one is only about 6” in diameter. Also, it’s still pretty holey, would not recommend using for a pot holder unless it was backed with another layer. Should be fine as a trivet.
