Here is how I do my binder:
I take the catalog apart and cut into separate pages.
Catalog cover goes into the outside viewing cover of my three ring binder:
I then put each page in it's own page protector and insert into the binder.
This keeps me working in one catalog for the whole time it is active. If I run into a customer with a question that I would normally jot near an item I use a small post-it note that easily removes once I have dealt with the customers' issue.
In the front inside cover I keep a copy of a spread sheet that I made (using an idea from Laura Aridgides, my director). The spread sheet includes the dates and times I want to have parties. That way people are not looking at all the days in my date book that I might not want to be available nor are they seeing private appointments or info. Due to the fact that hubby and I share one vehicle now and his work schedule is horrid (I never know what time he will be home) I only schedule in home parties for the weekend.
After the catalog in my binder I keep my planner that I printed off from our Thirty-One Today website. I printed the cover on card stock to make it a bit more easy to find with-in the binder and put it in a protective sleeve. I also put a divider in.
I use the information given for that season to write any dates in the planner. Also, at the top of each month I write that months' sale.
I keep training materials/print outs etc. in a separate three-ring binder. That keeps this one from getting too bulky. When I go somewhere I like to grab my "mobile" office in a bag and take it with me. That way I have a catalog or two and other might be needed items with me.
