The wool felt mat is apprx. 1/16", or a bit less due to the felt compressing. I use one and/or two of the same mats along with an 8 ounce record weight. I suppose that garment/upholstery wool would work if thinner mats/shims are required. Not thinking I recently discarded a moth damaged Winter weight Burburry wool suit (should have saved a few 12" sqaures of material from the back of the jacket).
The cork I purchased (to make the Spot Mats) was spec'd in millimetres, but I've since tossed the packaging. The materials look to be approx. 1/16" and a bit less than 1/8", so figure less than 1/16" difference between the lower/higher mats.
A simple Spot Mat can be made with a sheet of paper and cork "rounds". Not very durable, but it will allow you to see if the design works with your deck. I've also used felt Spot Mats, but prefer the cork versions.
Not a perfect solution, by any means, but the added height does improve the sound of thin LP stock quite a bit.
