I suddenly got on a scrubby kick. I can make one in a couple of hours. I give them away to my friends and suddenly, they want to purchase more as gifts for their friends, or they just want more for themselves. I even had one who accidently put one down her garbage disposal and needed another. I had a booth at a craft fair last Christmas and sold them for $5.00 each. I know that is really cheap for the time and effort. However, I am thinking that I knit them because I like making them, not to make money. So anything I make is gravy, right? I would be knitting them anyway, and I am not going to be using them all myself. (By the way, I hate cleaning) One skein can make three scrubbies with the leftover used to make scrapy ones. You need to use the specific yarns called scrubby. You can purchase them at Michaels or online in a variety of solid or variegated colors. There are some wonderful colors online that you can't find in the stores. I went wild last year and went wild with buying scrubby yarns.
The pattern I use is https://www.ravelry.com/patterns/library/garter-stitch-round-scrubby. However, there are several varieties on Ravelry. There is a square scrubby that you can probably make in a hour or less (https://www.ravelry.com/patterns/library/square-scrubbies). There are also some fun pattern in the face of an owl, a tomato, a puppy dog, a kitty cat, and a flower. I hope to make some of those one of these days, but this pattern is my "mindless" pattern.
In fact, I discovered that I can complete an entire scrubby on the drive from Littleton to Fort Collins Colorado. My son live in Fort Collins so it works out perfectly. By the time we finish our visit, I have two additional scrubbies, as well as any I knit while I am there.
And don't forget all the patterns of scrubbies that you crocheters can use as well. I can crochet, but I prefer to knit. I learned to knit and crochet at the same time when I was a preschooler from my mom and grandma, but for some reason, I liked the look of knitting more. I learned to knit making Barbie clothes and knit clothes were less bulky.You do have to use the specialty yarns made for dishcloths but there are lots of them out there. Michael's has lots of scrubby yarns, many in bright vibrant solid colors and several variegated ones too. You can also order many online as well. I really like the brand called Jubilee Yarn Scrubby Dish Yarn. It has wonderful colors in more muted colors. I don't like the 'sparkle' or 'eyelash' ones, but that is a personal preference. But I warn you. Searching for scrubby yarn is a big rabbit hole to fall into!So dive in and enjoy yourself!
