I recently realized how wasteful I was when it came to sponges. They get dirty so fast and there is really no way to sanitize them. So what to do? Stop washing dishes...no! It relaxes me...one thing I actually enjoy doing...I know I'm weird. I decided that I would knit something to replace them, it was really simple.
Basically knit (or crochet) a square double the size of a regular sponge, then fold in half and sew shut...your done! I used cotton yarn so that I could just throw it in the washer and dryer. It doesn't dry out very well so I recommend making at least three depending on how often you do laundry. I also made one in a different color for the bathroom, this way I will never get confused. I'm somewhat of a germ freak when it comes to certain things, toilets being one of them.
I have been using these for the past 6 months and they have been working great!
