Based in Portland, Kiriko is an apparel shop specializing in vintage and modern Japanese fabrics. I’ve bought a few items from them before (tote bags, handkerchiefs), and they threw in one of these extra small patch kits with one of my orders for free a while back.

Here’s the description from the product page:

Mottainai, it’s a phrase in Japan that means “waste nothing.” It’s a value we live by here at Kiriko, we save every piece of fabric, with the intention of reusing it in the future. This kit represents our hope that each piece of fabric from our studio has a purpose and a story that will be continued. If you have a piece of clothing that needs mending, these patches will add that unique touch.

The 3×3″ patches (five included in the $8 kit) make great and unique bookmarks, too! You should also check out their notebooks and other stationery items.
