Here is a popular crochet pattern, from Maggie's Crochet: Nylon Pot Scrubber.
I made this pattern, but not quite as directed because at first I didn't have a size N hook, then I couldn't find 2" nylon netting. Here's a photo of what I made, with the descriptions below.
Starting on the left, the blue is with Yarn Bee Scrub-ology Scrub It yarn and a size N hook. I bought a new skein for this because I wasn't sure if my leftovers from another project would be enough (I'm fairly certain I only had a few yards left). This yarn is a scrub yarn, so you want to protect your fingers and work slower so you don't rub your skin raw. This skein cost around $4 full price (79yd), and special yarns don't always go on sale with the regular but you can always check!
The yellow and green is with two strands of Yarn Bee Scrub-ology 2.0 yarn, and the yellow is with just one strand. These are using a size K hook. These were made with leftover yarn from another project - you can make a lot of scrubbers with one skein of this yarn! A review HERE says they made 7 scrubbies from one skein but I don't know what type they were making. I don't have a photo of the wrapper for this one since it's leftover yarn, already unwrapped. Same warning as the previous one, work slowly and use a thimble or something to protect your fingers so they don't get rubbed raw. Looks like the pricing is about the same as the other Yarn Bee, so about $4 per skein. I think you can make more out of this one than the other because I'm fairly certain the yardage is a bit longer but I can't find the yardage anywhere. The thinner skeins usually have much more yardage on them.
Lastly the big green is using 1.5" x 10yd organza 100% nylon ribbon and a size N hook. This one is only one-sided because I ran out of ribbon! Yes, that means you'd need 20yrds of 1.5" ribbon to make one of these scrubbers. That is about $8 of ribbon (full price - please look for sales as craft stuff is always getting discounted). But you actually might need more because I only have a small portion left over (wraps around the spool 3x) and that is probably not enough to connect the two pieces. It might be, combined with the leftover from the second spool you will need, but you'll be tying the ending together so there'll be knots on your border. Not the best. I will add that crocheting with ribbon is annoying. I would charge extra if someone wants an item crocheted out of something that's not yarn.
