Things found on the floor of my studio: A blue letter O; two puzzle pieces; a small rocket ship; a cardboard tile with the word COMETS on it; a very small sticker stuck to the floorboards that says "Road Closed" in black against orange; another sticker, artfully pressed into a knot in the floorboards that says "YES" in all caps; a small black wheel; a spool of turquoise thread; a solitary striped sock; a red matchbox car; 1 pacifiers; 7 hair ties; countless snippets. I can only trace the origins of the final two from that inventory. This is what happens when I work in my studio with children underfoot.
It's such good practice though, to slow down enough to take an inventory of the details around you. Try it: Can you notice five unusual things within an arms reach? What are they?
