List of materials (might miss something - it always happens!). These are just pix I took off various sites and they're a mishmash of colors and sizes due to my inherent laziness. ;-) Please do look in Lowes or Home Depot for these items because all of them are usually there and you can make a fun game out of finding them! Lowes has a better selection of parts like this, as HD has decided that allocating real estate to $2 parts doesn't make them rich enough anymore.
Good luck and keep asking if you need to.
