sounds like a nice idea. i guess you could pretty easily do it at any form w/ a metal yardstick to push a line from one sheer split to the other side and back again on the other side of the form and then seesaw the line over. or even leave string loop in at each form. or say even better a continuous weave of line from one side to the other at alternating forms. sounds like a keeper!

and i guess at any tough one, a little application of heat accompanied w/ the line and the smacking'll open anything up.

i have an upcoming situation w/ very very minimal access but requiring major or even excessive form control and adhesion. this idea will be absolutely perfect for it.
thanks
