I love older glass. It has a thickness and quality to it that I admire. You lift it, and it has a "heft" to it. The same holds true with older bottles. The top image is from my Modred12 store. It's a lovely amber brown bottle, that comes from the 1960s at the earliest. It can stand by itself as a pretty item, but it can also work to hold flowers, whether a single bud or a bunch.
I have a similar bottle for sale as well, and they could "bookend" a larger item, whether a bigger vase or pottery piece. You can even mix and match, and the Good Seasons bottle would work with the brown bottle. It can be a eclectic mix, and one that will stand out.
So keep this option in mind when you're out looking for estate sale finds. Older glass can be beautiful by itself, but could hold flowers, or other pretty items such as glass beads, pebbles, or other small pretties. The quality of older glass is to be admired, as are well-made vintage items in general.
