Wrong. For some reason those little bags are harder to find than the Loch Ness monster! Which set me upon a months long search for a replacement. And ended here.
When you can't find what you are looking for - make it!!
I took a cloth place mat, folded it not-quite-in-half, sewed up the sides. Folded the longer side over a plastic hanger, and sewed that in place.
Voila, a simple yet quite cute (in my opinion) - and very handy - clothespin bag! At a fraction of what a new one would cost.
