Sorry, I don't have a measurement. I keep several thicknesses and use something that's deeper than the cutout the felt goes in, but not so deep a small spring clamp won't compress it flush with where the Ecsaine glues on. I cut the felt very slightly narrow of the backcheck, and glue it on first. The Ecsaine is cut very slightly wide (looks neater when the felt isn't slopping out the sides), and the top is glued first. After drying, the Ecsaine is stretched and glued at the bottom, with a spring clamp and a flat maple caul. When the clamp comes off later, the felt springs the covering up into a nice rounded pad. I thought I had some photos, but I don't find any. Ron N
