Sometimes when things go bad, you have to take drastic action. Here is Deco, as it was on Saturday. I completed one side, but found that I had to use a bit of tape to hold the pieces and keep them from falling off the sides.
Unfortunately, the closeness of the pieces would probably mean that grouting this piece would look really strange. So I decided to take the drastic step to soak this in hot water to unglue it.
I then reglued the pieces, but with some space between them for the grout. I think it now has an intimidating feel to it. We'll see where it goes.
