I actually had planned to abandon store-bought, single-use cotton pads for a while, but I just could not find the motivation to finally start making my own washable ones from cotton leftovers. However, sorting my stash recently made me aware of the huge amount of cotton leftovers waiting to be made into something. You can find quite a few (free) patterns for this crocheted version on Ravelry which are actually pretty similar. I chose one from 2013, DIY: Reusable Cotton Wool Pads by Lyndsey Haskell. The pattern is easy to follow and the pads are fast and fun to make. My first bunch comprises 15 ones which used up 58g of DK weight cotton yarn in sum. I have not tested them yet as I need about 50 of them to start the using/washing cycle in a relaxed way. So, there will be more of them, soon.
