When you spend money on expensive furniture, the last thing you want is to see water marks all over it. And while you could solve this by never drinking water again, we don't think your body would thank you for that! So, it might be time to invest in some coasters. But you don't have to go to a store and buy some, as the only investment you'll need to make is a glue gun, some wool, and some felt.
By gluing the wool onto the felt in a spiral pattern, you'll be able to make your own coasters in no time. Of course, you can choose your own color scheme too.
