We construct some examples of explicit solutions to the problem [ min_gamma int_Omega d_gamma(x),dx ] where the minimum is over all connected compact sets $gammasubset overlineOmegasubset{mathbb R}^2$ of prescribed one-dimensional Hausdorff measure. More precisely we show that, if $gamma$ is a $C^{1,1}$ curve of length $l$ with curvature bounded by $1/R$, $l leqpi R$ and $varepsilonleq R$, then $gamma$ is a solution to the above problem with $Omega$ being the $varepsilon$-neighbourhood of $gamma$. In particular, $C^{1,1}$ regularity is optimal for this problem
