Hello Jim,

Thank you for the detailed reply. I have ordered some from Thorlabs today. I also managed to contact Mike today at The Leather Supply House and ordered some Motor Cloth, 030-5 Rubberized Cloth Superfine Pneumatic Cloth, and 030-6 Silk Pneumatic Cloth. You are right, the BR5 from Thorlabs is a good deal (although they only ship UPS or FedEx).

Cheers,
Clarence
