I'd switch up your featured listings to your top sellers: The page holder thing, a coaster, and two rings. The table doesn't fit in with the rest of the items in your shop, and the titanium ring is a really different look than the wood ring (although it's cool that you know how to make both).
Consider making some coasters ahead of time, too, so that they're to the customer faster. It seems like you have no problem selling the coasters, and while it makes sense to make rings to order it make less sense to make coasters to order.
