I forget where I read this idea. It may have been on misc.kids, and
the originator will mail you a response as well. Just in case (s)he
doesn't, I'll try to summarize what I remember.
Take some of that metal or plastic outside corner strip. It is about
3/4" by 3/4". With small cement or brick anchors, or burred nails,
attach this to the brick corner of the hearth. Use as few nails as
will hold it securely. Then take the foam pipe insulators that you can
get at a hardware store. Cut out one quarter of the insulator, and
glue it to the metal stripping. This provides a nice cushioned
corner. When you are ready to remove it, all you will be left with is
the few small nail holes you used to hold the metal stripping in
I'll _try_ to do an ascii sketch, but who knows if it will help you
understand what I mean!
