I’ve exploring the making of dryer balls. These balls are used to soften items in the clothes dryer and use less fabric softening products. There seem to be a number of different methods of making them.
Some are made of WOOL yarn stuffed into a knit casing; much like the Ball Christmas ornaments. Others, are yarn wrapped into a ball and secured with sewing. Some, are simply a ball of roving and then needle felted.
All, are then felted and dried. Some are some of this and that technique.
This is how I made mine. I wrapped wool yarn around a wool core (a scrunched up wool swatch). I then Needle felted some fleece over the yarn ball. Washed it in the wash machine and secured any loose ends with the needle felting tool after the drying process.
I have read that using acrylic yarn for the core doesn’t work very well, as it is not heavy enough for the drying action in the dryer.
I think this would be an ideal way of using up wool that has deteriorated after an encounter with moths.
