Step 1: What you will need
1. Some good Australian red wine. I prefer shiraz from the McLaren Vale in Victoria, but a Cab Sav from the Margaret River will also do nicely.
2. Two thin bent metal book ends.
Surprisingly, for this instructable you will not need...
a laser cutter,
a 3d printer,
an altoids tin,
Step 3: Stack bottles
Adjust the book ends so they hold the bottles snug.
Add a second row of bottles.
It is important that you do not try to stack the top row first.
