I am an only child. As such, when my mother has something she no longer wants/needs/has room for, I am the designated recipient.
Usually, I am certain I will never have any need of the item in question, and usually, my mother is just as certain that it will become a necessary and integral part of my life.
In the matter of the Super Wash, it turns out my mother was right.
Today I used it to felt what amounts to a crocheted bowl, but which is actually a test to determine what size to make a cat bed.
Here is a photo of the cat in question:

Stripes is our household cat, and she is usually somewhat cross with me. Her favorite way to express her displeasure is to ignore me the entire day, and then paw at my bedroom door from 3:00 am to 5:00 am. In an attempt to ameliorate this behavior, I am designing a cat bed made of Lamb’s Pride worsted weight wool. I plan on scenting it with catnip and putting it out for her when I go to bed so that she has something to occupy her while I sleep:

situated the Superwash:

added tennis balls to the washing chamber to increase agitation:

and then added the item to be felted and some water:

A couple of thousand (maybe only 1500) turns of the handle later, here is what I had:


Overall, the results you can get with the Super Wash are good, and you have more control over the process than you do when you use a regular washing machine. You are, however, limited to felting objects that both fit and can properly agitate in the Super Wash chamber.
