 Now for a little more detail.

+Choose a metric on $X$, and let $\cU_\gamma$ be the open cover of $X$ by balls of radius $\gamma$.
 By Lemma \ref{extension_lemma} we can restrict our attention to $k$-parameter families 
 $p$ of homeomorphisms such that $\supp(p)$ is contained in the union of $k$ $\gamma$-balls.
 For fixed blob diagram $b$ and fixed $k$, it's not hard to show that for $\gamma$ small enough

 \begin{proof}
 
 There exists $\lambda > 0$ such that for every  subset $c$ of the blobs of $b$ $\Nbd_u(c)$ is homeomorphic to $|c|$ for all $u < \lambda$ .
-(Here we are using the fact that the blobs are piecewise-linear and thatthat $\bd c$ is collared.)

 We need to consider all such $c$ because all generators appearing in
 iterated boundaries of $p\ot b$ must be in $G_*^{i,m}$.)
