Crochet Cotton Sponges - Double Thick

So, in an effort to be a little more eco-friendly, I decided to make and try out using crochet cotton sponges for washing/cleaning etc. They've turned out to be great! I used a special stitch that makes a single crochet fabric that is double thick. I love how the texture is great for cleaning up and protecting surfaces, and the cotton is so absorbent that it make clean ups quick!

Here is a link for instructions on how to do the double thick fabric:

Here is the pattern that I use to make the sponges:
