Cute earrings! Made me click! Loving the owls too!
To help with pricing... think like a buyer rather than a seller... think, "what would I pay for this?"
You can research etsy for similar items... search for anchor dangle earrings & see what the range is.
You don't want to undercut yourself for your materials & time involved though...so don't undervalue what you do.
For shipping, you can take a package to your post office & have them weigh & calculate the shipping to get a broad idea for what it could be.
I ship smallish items too & my shipping is generally $3.25 for the first item because of the way I package my items in individual boxes & always include a card + I live many miles from the nearest post office, so gas & travel times are also considered.
If you live close to your post office & package your items differently, you may be able to charge a bit less than I do.
Good luck with etsy!
