4" and wider thins are resawn from a board thick enough to produce 2 pieces and then planed down to a finished thickness of 1/4". This milling process releases tensions in the board and may well induce slight cupping and/or bowing in the finished piece. These movements are normal and not considered "defects". They will not be grounds for a return or refund.
I love the materials I received, it is even better than I was expecting, I only with there was more information on how the material is made, and maybe some laser settings for starting out.
I have already placed two more orders in the past week.
