That was very clear wasn't it? It's certainly not available anyplace else. When I commissioned my chair back from RM the end of last year he had mentioned that he had just enough of the fabric left to do one seat cushion and one back. From that and other posts scattered around though it looks like the run of checkered fabric may be running out so it's not clear at this point how much of it is left.
It was great that STC was able to commission a US mill to make a run of this beautiful fabric and that there was plenty enough of it to share at one point. Cheers to everyone involved with making the checkered fabric available. Another job well done!
