We found these great close-up mats produced by Undermagic® in Spain. This standard size measures 38,5 x 30 cm. and is ideal as your "close-up scene" for routines using cups and balls, coins and cards.
 
The material is "Neoprene", commonly used for wetsuits, but it is the ideal material to use for close-up pads:
The base is non-slip rubber with tremendous power, the surface is made of synthetic nylon fabric. Soft touch and extremely flexibility, and best of all: it does not wrinkle! You can fold it, crumple, crush ... and it always is perfect and ready for use when needed. 

It may occasionally happen that a large and continuous pressure, causing some surface marks visible. To correct this, you just have to extend it on the table and within hours the table will have completely regenerated!
