I created a couple of black rings made out of resin some time ago and filled those up with 1 layer of colored resin, some attributes and a final layer of clear resin.
I hate airbubbles and there are a lot in the pendant with the dog in inside.
There is some lint cured in the pendant with the cat inside ....
... and I haven't sanded these black resin rings enough now I see them at daylight.
Now I'm thinking of wooden rings instead of resin rings. They are cheap and it's less work (!).
If I list an item on Etsy, it has to be perfect.
But soon there will be a new listing coming up with pendants like these.
