Here’s a story about wholesale from the early 70s
I had an art professor friend that taught art and ceramics as well for a short time at a JC in our area.
He decided to build a kiln (I was one of the crew that later dismantled it) and get a slab roller and start making flat items. He got some samples together then decided to head down to SF wholesale gift show one winter to get some orders. His plan was to hire students to crank out the work.
He took all the orders he could-at that time I think it was over 80K in orders which is 1972 or 3 was no small number. He came home with several years’ worth of orders to do that spring and fall. He hired whomever he could find to crank out wind chimes and X-mass ornaments etc. In about 3 months he had a mental breakdown as there was no way he could ever get the volume of items needed. He sold all the clay stuff bricks slab roller clay etc. and I got the job of taking the kiln down and the bricks away.
Just stating that one needs to know your output before taking orders of anything.
I can tell it now, as he is not on this planet anymore and theirs a great lesson here.
