Summer Season Tam

I was never a great fan of Piers Plowman, but the opening lines are lovely and have always stayed in my head:

In a somer season, whan softe was the sonne,
I shope me into shroudes, as I a shep were,
In abite as an heremite, unholy of werkes,
Wente forth in the world wondres to here,
And saw many selles and selcouthe thynges.

So here's a tam for William Langland to wear to brighten up his hermit's garb. The dyes are madder, poroporo, indigo, weld and onion skins. The top shows trees, flowers and flowering vines and the underneath has a pattern of butterflies.
