I simply enjoy painting and decorating..starting again when the room turns a bit boring and off I go to my local Lowes or Home Depot ready to create a new color scheme for my home.  Once I decide on paint colors, I prep and paint away.  I always ask for a few extra paint sticks and immediately dip two into the clean gallon of paint.  Once dry, I write the name of the paint, number of the paint & sheen - brand as well.  The first stick I store and use as a paint reference.  The second is the start of my grand color palette!  This stick goes with me to my favorite outlets, Home Goods, and TJ"s.  I have also used popsicle sticks in lieu of paint sticks - they seem to fit better into smaller purses, especially if you are in the city and on the hunt for a unique trendy lamp or new blend of pillows!  Don't worry about writing info on the smaller sticks, it's really just for a decorating tool of sorts - helping you pull in new colors as well as add depth and dimension to your new room!
