An occurrence I see a fair amount is hands landing on the modules when
somebody leans in to look. This happens mostly (but not exclusively)
from youngsters enthusiastically approaching the layout. As all that is
holding the layout is Unijoiners, It is pretty easy for the layout to
be knocked out of alignment, or even modules separated.
I try to make sure that modules are located eight or nine inches back
from the front edge of the table, so that there is a safe place for
hands to land -- on the table, rather than on the modules. This should
also hlp with dangling straps and similar difficulties. It's not always
possible, but whatever space that you can add between the table edge
and the modules helps.
This obviously doesn't work for single table width, up and back
layouts, but is good practice for any larger layout.
