"Strange, Not Normal, but Cool"
That's the way one source defines quirky. I prefer to focus on the cool, unusual, and unique aspects of those things we call quirky. Many handmade items can be called quirky.
One of the benefits of handmade products is that many such items are unique and cool, the definition of quirky. Unusual color combinations, interesting use of materials, or a focus on shapes may define such creations. Many of these cool and unique items can be further adjusted to make them just what you want.
In one of my online shops I sell a line of quirky pendant necklaces. They are unusual and can be customized with your choice of color in the leather cord necklace as well as in the length you choose. Quirky meets customization! When you work with the seller of handmade items there is often the possibility for customization, perhaps for a small fee.
Need it longer, shorter, a different color? Why not ask? We who create quirky items do love our work and will try to work with customers. There are limits, of course. I wasn't able to make a blue crystal pendant turn white, a bracelet shortened to 4 inch length and still be closeable, or a cord swapped out on a necklace whose beads were too tiny. But many other requests were met.
Here's where you can find these and more quirkly items.
