Hi All,  With regards to cutting cotton-backed pneumatic cloth with
a laser cutter, I can attest to the quality of work that John Grant
has done (see attachments).  As you can see in the pictures, these
facings are rather small, but the cuts are very precise.

I might also mention that cotton-backed striker pneumatic cloth is
now available at Player-Care.

Musically,
