This morning I reorganized the spindle display again.
It's a good thing I did because I found this:
A full spindle of Merino wool with two pinprick holes. Something - a critter - bit and burrowed it's way down into the spun singles chewing and destroying the handspun as it went. I know!
I quickly removed and bagged the wool and spindle and cleaned the area. Fortunately, I did not see or find any live critters or casings.
This evening I wound off the remaining three Supported Spindles and placed the storage bobbins filled with the Merino wool in the freezer. The singles I wound off were strong and intact, no thinning areas, no holes.
I am going to have to be more careful and not "display" my spindles clothed in handspun; naked is best.
