Silken Butterfly and Merry Muslin Moth

I have a daughter made of silk
And gossamer and such,
Her sister is a muslin child,
As sturdy to the touch
As homespun is, as warm, as dear...

Beloved both, this much
They've taught me, silken butterfly
And merry muslin moth,
That silk and muslin, woven together,
Make a lovely cloth!
