A spice-saving solution...

So, we've got kitchen cupboards.  But they're on the full side.  One of them was, until today, rather crowded with spice jars, as we could only fit a few (14ish?) on our spice rack.
So I made a new one.
Simple enough, some stripwood, some dowel, and some little lathe-type things.
A bit of measuring, sawing, drilling and hammering later...

Ta-da.  Space for 30 (ish) spice jars.  And yes, we do use most of them!
The sides and shelves are the same wood, nailed together.  There are thin strips nailed to the back (two to each row) to stop stuff falling off the back, and the dowels you can just about make out in the rubbish photo are just pushed into holes in the side bits that were drilled using a drill-bit the same size as the dowel.
Pretty easy task.
