Every few months, Dollar Tree puts out seasonal collections of kitchenware that usually include glass bowls, glass plates, mugs, small and large glasses, kitchen towels, oven mitts, and pot holders.
I've seen a range of designs, including autumn leaves, sunflowers, lemon trees, holly leaves, and polka dots.
If you're going for a simpler look, try the clear glass plates and bowls available year-round. I think they're very aesthetically pleasing, and I've also found them to be super sturdy — I've yet to break one.
