suggestion -- Can storage

hello ana and everyone

my wife and I are (not so extreme) couponers, and we are saving BIG money with coupons... but our poor pantry (a cheap bookshelf/cupboard from walmart) is falling apart.

I would like to make can-rotating shelf similar to:

however I would like to make it into a built-in, floor to cealing, kitchen cabinet... I also figured that you (ana) would like to build one for your moms!

or something like this...

that could hang on the back of the door

you might even be able to build this into the pantry as that shelf-wall that you were designing (behind the door)

what do you think?
