I know this was posted before, but I thought it might be useful to re-post as this will save quite a bit of money on your shop supplies. I ordered MM from www.internationalviolin.com in Baltimore, MD. They carry all of the meshes from 1500 through 12000. Their sheets are 6X12 and a sheet of each ran $35.10, postage and handling included. It arrived in 2 days, of course I live nearby, so USPS may take a bit longer to get to you. I use the paper cutter at my local Kinko's to cut it to size...the manager loves it because it sharpens his cutter.
