    Hello,

    Does anyone happen to have ITF/USTA rules about string and stringing? In particular, is it legal to make your own string by twisting a pair of very skinny string together? Essentially make your own multifilaments.

    Many thanks.

    AFAIK the rules only cover stringbed density, protruding devices, and interweaving, not the physical composition of the string.

    I can't find any rules other than the below passage from this link:
    http://assets.usta.com/assets/1/15/ITF - RoT 2010.pdf

    "The hitting surface, defined as the main area of the stringing pattern bordered by
    the points of entry of the strings into the frame or points of contact of the strings
    with the frame, whichever is the smaller, shall be flat and consist of a pattern of
    crossed strings connected to a frame and alternately interlaced or bonded where
    they cross. The stringing pattern must be generally uniform and, in particular,
    not less dense in the centre than in any other area.
    The racket shall be designed and strung such that the playing characteristics are
    identical on both faces. The racket shall be free of attached objects, protrusions
    and devices other than those utilised solely and specifically to limit or prevent
    wear and tear or vibration or, for the frame only, to distribute weight. These
    objects, protrusions and devices must be reasonable in size and placement for
    such purposes...."
