I've made tons of these. They work absolutely wonderful on dishes and people. For dishes I use cotton yarn for one side, and tule on the other side. For people scrubbies I use tule on both sides.
Tule is weird to work with. It feels strange, and it's more "bulky" than even 3 strands of yarn. Also a stand of some kind, to hold the tule so it doesn't bounce all over every where.
These take me maybe 20 mins to make, start to finish. I'm not the fastest crocheter either lol.
They are washable as well. I use a laundry/delicates bag when I wash mine.
