Karen Pasieka (subtledetails) seems surprised that her little art tiles sell quickly. “Nothing overly unique about this design in terms of my own collection, but they have been very popular so it can’t hurt to have another one available to purchase!” she says.

This Hydrangeas is a work in progress. Its delicate petals jump over the edges of the softly gradated tile, bursting with delicacy and energy. No surprise to us that they’re popular. Here are more of them.

Are you sometimes surprised by what’s popular in your work? It pays to listen to your customers.
