Most days, when I take the dog for her morning walk, I go past several little utility hole covers and I've been fascinated by the keys pattern around the edge of them. When I decided to make myself a Viking apron dress to wear at Drachenwald's 30th Anniversary celebration, I wanted a trim that drew on something distinctly Irish (given that we've been living in Ireland since the end of 2021) and what could be more Irish than Uisce!

I took a photo of the hole cover and roughly sketched it out on a piece of paper, then drew the draft out. I chose blue, black and white, as they're my colours within the SCA and my arms have a blue river running across the middle, rather like the blue waves across the band. It's mostly a diagonals pattern, with a few areas of 3/1 broken twill double-face to produce white areas and blue lines parallel to the selvedge.
If you chose to weave this draft, it would definitely benefit from the use of a row marker of some type. The horizontal ruler in Tablet Weaving Draft Designer is excellent for this.
