Thankfully we don't actually have any moths but I can't resist a
literary allusion when I think of one. But a few friends recently have had or feared moth problems so I decided on pre-emptive action and sewed up some lavender sachets. I wanted to use a fine, light-weight fabric so that the lavender scent would easily escape, so to speak, and decided upon some Swiss cotton handkerchiefs that I bought at op shops in Zurich when we visited a couple of years ago.
A couple of them weren't in very good condition after going through the wash but that was ok, I just cut some fabric out around the damage and sewed up the sachets. I bought a set of fine sewing machine needles especially for the task and promptly misplaced them. I had an inkling that for such a light-weight fabric I should alter the tension of the presser foot pressure or some such but, well, I was too lazy to look it up. So I just sewed - no problems.
Now each closet and cupboard with woollens therein also has a lavender sachet and (I hope) no moths.
