    Hello again Will.  You may have tried to cast too large a piece. 
    Try to close your eyes and think like molten metal, which is cooling
    the minute flame leaves it.  Imagine trying to go from crucible to
    the outer limits of the model - how are you going to get there ?  Are
    there plenty of sprues to give entrance to each of the mesh areas?  
    A better way than sprueing such a thing is to simply weld the end of
    each thread to the sprue button itself - the large size center button
    can allow this.  You could also thicken the mesh by adding wax to it
    - dip it - or spray it repeatedly with a thickener like lacquer,
    paint, whatever.  Even nail polish. ( Mind you don't hang over the
    burn-out fumes.) 

    You might cruise the aisles of a craft-supply store.  There are
    plastic meshes of many sorts for other purposes than fruit bags that
    could work better for you - heat and form them.  I have found the
    plastic net bags wonderful for roller-printing metal.  One looks
    almost like alligator hide.    Have fun with your experiments,  and
    do keep notes. You think you'll remember it all   but you won't. 

Pat
