You won't browse Etsy for long before running into the abbreviation "OOAK." I usually pride myself on being able to figure out abbreviations and acronyms, but I ended up Googling this one. OOAK = One of a kind. I have a couple of items in my shop that are OOAK. The newest is pictured here. I didn't list it that way, but I don't think I'll be making more. For me, a one of a kind item is usually an accident or experiment. I start playing around with something and end up not writing down the pattern. This brooch started when I was showing a friend how tatting looks. I kept making ring after ring, ending up with a layered looking flower, and then secured it to a pin back and added a turquoise bead. Kind of weird and messy, but I love those colors together. I actually prefer thinking of it as a one of a kind rather than an experiment or accident anyway.
