I love making these! You can make 2-3 per yard of material.
First you need a size K crochet hook.
Then, get a yard of "Net" material at Walmart or Hobby Lobby. It comes on a bolt like fabric. There are many types of tulle but this is what you need. It has bigger holes and coarser. Of course, you can use the softer tulle and use as bath scrubbies. This type of netting is only for kitchen use as it's too coarse for the skin.They sell for about a $1 per yard.
I like to buy it in one yard increments because I like the size that one yard makes. If you buy it let's say 2 yards long, then you're scrubby will be larger. That's because 7 strips equals 1 scrubbie. I'll explain more later.
Take your material and unfold it until it looks like it did when you got it cut at the store. There should be a fold at the bottom. I then like to fold it up once more and use clothespins or weights to hold it all in place. Don't try to cut it without doing this first, because the material will move and it will be a mess. I threw out many yards of material in frustration as I tried to cut it before doing this step. I was left with a mess! lol
The picture is a little hard to see but you just lay it like this:
And then fold up once more. You can even fold up again, but I don't.
I cut it in 1 to 1 1/2 inch wide strips.
Don't worry about measuring each strip. If you have to, measure the first one so you know about how wide to cut it and then just eyeball it.
Here are the strips ready to store in ziploc bags ready when I need them.
If I have multiple colors, I'll keep them in the same bag. Three sets will fit nicely in a ziploc quart sized bag.
Now, that you have 7 strips ready to go. Here's what you do!
Take the first strip and chain 3. Then make 5 single crochets in the first chain. Try not to pull too tightly when you get done with each one. You want it to stay loose. If you pull too tight, you will break the netting material. If that happens, no big deal. Use the method I will teach you and you won't have any waste.
After you make 5 single crochets in the first chain, then continue around and make 2 single crochets in each chain.
Before you run out of netting when you have about 2 inches left. Take the next strip, and lay it underneath (or on top) of the previous strip. Sorry it's kind of hard to see.
I then take it from the top and fold it down. Then, I take my finger and give it a twist to hold it in place.

Then continue making 2 single crochets in each chain around.
Keep going until you almost run out of material again. (This method keeps your work from looking knotty and will never unravel on you. - I didn't understand how it wouldn't come apart on itself but in all the months of using my scrubbies, I have never had one of them fall apart.
When you almost run out of netting, connect it as I said, but this time change to doing only one single crochet in each chain around. You will repeat this procedure for the next 4 strips. It will start to look kind of like a bowl.
And for the last strip, (continue to attach as I said) you will make one single crochet in every other chain. This will start to close the bowl up. Then, when you close up the hole, you will poke the crochet hook through to the other side and pull the netting through.
And there you have a nylon net pot scrubber!
