  We develop two new methods of constructing sequences of manifolds with
positive scalar curvature that converge in the Gromov-Hausdorff and Intrinsic
Flat sense to limit spaces with "pulled regions". The examples created
rigorously within using these methods were announced by us a few years ago and
have influenced the statements of some of Gromov's conjectures concerning
sequences of manifolds with positive scalar curvature. Both methods extend the
notion of "sewing along a curve" developed in prior work of the authors with
Dodziuk to create limits that are pulled string spaces. The first method allows
us to sew any compact set in a fixed initial manifold to create a limit space
in which that compact set has been scrunched to a single point. The second
method allows us to edit a sequence of regions or curves in a sequence of
distinct manifolds.
