This solution is derived by treating the nonlinearity in bending elasticity through the (topological) Bogomol'nyi decomposition technique and elastic compatibility. We recover the ``hat-model'' approximation in the limit of a small latex bead and find that the region antipodal to the grafted latex bead flattens. We also derive the appropriate shape equation using the variational principle and relevant constraints.12 pages, 2 figures, LaTeX2e+REVTeX+AmSLaTeXSoft Condensed MatterExactly Solvable and Integrable Systemstext
