A Speckled Striped Path

I set off away from the sofa cushions to see how far the wooden floor stretched! Right by the edge of the hallway rug, a bright strip of sunlight caught something round and flat. I leaned all the way forward, nose nearly touching the wood. It was a giant striped button, shiny red with navy blue ridges! I planted both hands on the smooth rim and gave a big shove. It rolled forward with a gentle clack, leaving a clean trail through a tiny patch of morning dust before wobbling to a halt like a tiny shield.
