craftgrrl | two questions. i know youre excited.

(1) I asked about this once and nobody offered any ideas. I bought a jewelery box and didnt like what was on top of it so i took it off and planned on painting it and adding a stencil or something. I changed my mind and decided on buying a mirror and breaking it into a bunch of pieces and then glueing the pieces on so it pretty much covers the entire top.
How should I go about breaking the mirror. Like should I put a towel over it or put it in a bag?

(2) I bought a pair of canvas maryjane/flat type shoes and they give me blisters on the back of my ankles. Does anyone know of a way to soften the top backs of the shoes or any other remedy or am I just going to have to use good old fashion bandaids everytime I wear them?

thank you :)
