  The skein module for a d-dimensional manifold is a vector space spanned by
embedded framed graphs decorated by a category A with suitable extra structure
depending on the dimension d, modulo local relations which hold inside d-balls.
For a full subcategory S of A, an S-admissible skein module is defined
analogously, except that local relations for a given ball may only be applied
if outside the ball at least one edge is coloured in S.
  In this paper we prove that admissible skein modules in any dimension satisfy
excision, namely that the skein module of a glued manifold is expressed as a
coend over boundary values on the boundary components glued together. We
furthermore relate skein modules for different choices of S, apply our result
to cylinder categories, and recover the relation to modified traces.
