How to make the sheets….
I took an old hand towel that we weren’t using anymore. Mine happens to be white (for all loads). To be honest, the base color WAS white before my kiddos decided to clean chalk (red and blue chalk) off the basement floor with the white towel–the reason that towel is now the dryer sheets towel. I’m not entirely sure it matters what color your towel is. I have never noticed any of the white transferring onto anything else – color or fabric.
I took the towel and cut it in half, and keep cutting until you have “sheets” that are around 2 inches by 5 inches or so (see picture below). I usually get around 20 sheets from each towel. The sheets do not need to be even; I have found that the 2 by 5 inch (roughly) size tends to work the best. It easily fits into your hand, you don’t loose them and they dry with the laundry. And your sheets are prepared and ready to go into the solution.
Once they are cut you can use them right away or you can run them through a quick rinse and spin cycle. I would NOT recommend running them through a quick rinse and spin cycle to get off any of the extra fabric from the cut sides – they become a ball of and tie all together. If you don’t mind cutting the string apart it works fine. If you choose to use them right away I would use them with a load of towels first – to make sure the amount of strings and little extra fabric from the sheets doesn’t transfer onto your clothes. I have never had this issue but better to be safe than sorry. Once they get out of the first load, clip off any extra strings. Your “sheets” are ready to go!
