The Undergrowth hat is leafy. Wearing this hat, you might even blend in if you were trying to hide in a shady garden. But why hide?

Inspired by the hosta plants that I planted years ago and come back each Spring despite my best effort to ignore the garden in favor of more knitting time, this hat is an ode to their tenacity. Hidden underground all winter, the good old hostas surprise me each year, part of the garden undergrowth.

The hat starts with a double braid -- because if one braid is great, two are fantastic. After increases for snugness, the leaf-inspired motif begins, appearing as if from nowhere. Neat lines of decreases are vines of the plant, incorporated in a way that gives this hat both a naturalistic feel, but also something very geometric.
