This may be a silly thing to post about, so bear with me. We don't have a dishwasher, so we wash all our dishes by hand. Over the years, I have found that a standard sized sponge is sort of cumbersome in the hand, especially when maneuvering in a small glass or tight spot. At one point I bought some mini-scrubber sponges, which were just right, but I have rarely seen them since.
Instead, I have just taken to cutting my sponges in half. The smaller sized sponge fits easier in the hand and you can use it almost as long as a full-sized, meaning you get twice the sponge for the price of one. It's just one of those little things that saves money and cuts back on waste over time -- thought I would share with you.
