 We claim that $J_*$ is homotopy equivalent to $\bc_*(S^1)$.

-(b) there are no labeled points to the right of * within distance $\ep$.

+Let $b$ be a blob diagram in $F_*^\ep$.
+Define $f(b)$ to be the result of moving any blob boundary points which lie on *

+(Move right or left so as to shrink the blob.)
+Extend to get a chain map $f: F_*^\ep \to F_*^\ep$.
+By Lemma \ref{support-shrink}, $f$ is homotopic to the identity.
+Since the image of $f$ is in $J_*$, and since any blob chain is in $F_*^\ep$
+for $\ep$ sufficiently small, we have that $J_*$ is homotopic to all of $\bc_*(S^1)$.

 We define a degree $1$ chain map $j_\ep: L_*^\ep \to L_*^\ep$ as follows. Let $x \in L_*^\ep$ be a blob diagram.
 \nn{maybe add figures illustrating $j_\ep$?}
