I took a sheer curtain that got a few runs in it with the help of a kitten. One side was still ok.
I folded it in half and cut 11"wide rectangles. The length was whatever my curtain length was halved, probably 25". I was able to cut three from the curtain avoiding the tears.
Fold them inside out and sew up both sides and then turn them right side out again. Super simple! Put produce inside and tie a knot to keep it in there. The produce is just visible enough to make out what it is. If there is a number the clerk needs to read, then I would probably not knot it since I am not sure I could make it out with the sheerness of this particular curtain.
