Mnemonic

You crack open a cocoon and discover a little surprise: one continuous thread spiraling inside. Pull that little thread and it unspools endlessly from the cocoon — miles of shimmering silk hidden in something so small.
Additional thoughts
Picture prying apart a fuzzy cocoon and seeing the glint of a single tiny thread coiled tightly within. The smallness of the cocoon emphasizes how little yet how long the thread truly is.
Quick recall
A cocoon hides a little Thread that unspools forever.
