Kitzini Baking Mats
Baking mats are great because you never have to grease a baking sheet literally ever. There’s a really popular brand (Silpat) that honestly I think looks a little too Home Depot for me, so I went looking for a better looking alternative. I found Kitzini, which has a nice logo typeset in Futura, and comes with two nice versions of red and blue. So besides these being IMO integral to baking (please don't buy parchment paper, what a waste 🙄) I also think they are very nice looking.
