The warp and weft are gray 22/2 Cottolin. The graphic is fingering weight wool. I'm using an Ashford Rigid Heddle loom with a 15 dpi reed.
I really like the process and the gauzy effect. I plan to do more of this.
Also, I bought a 25 dpi reed for my Glimakra loom.
And lastly, wool, alpaca, silk from Pittsburgh Knit Crochet Festival; Projects coming soon. :)
