It’s a little pouch with a clip to hold the small Klockis clock from IKEA, although this can be adapted to hold all sorts of different things. Because it’s small (and can be completed in just a couple hours), use stash yarn. Only a very small amount is needed.

This is knit from the top down and finished with a 3-needle bind off. The clip can be purchased from an office supply store. It’s just one of those clips that one puts on name badges. Then the pouch can be clipped anywhere so the clock inside is easily retrieved.
