Sent another Etsy pot off this morning. Seems this double boxing is costing more than the $9 shipping I charged. It was good to find out that the post office charges are based on the combination of box size, weight and distance.
I'm taking a "rest my back" break after trimming and waxing some pots and putting a couple of hundred pounds of Moon White through the pugmill a few times. It needed softening after sitting a few months. Soft clay, slow wheel works for me. As soon as my back goes out of spasm I'll head back to the studio to do some throwing.
It's going to take a few days for these muscles to get back in studio shape.
