The labels are laid out on a standard 8 1/2" x 11" sheet of paper and are made of a thin but strong plastic. The tabs have two printable sides... one for each side of the tab. After printing you just fold over the tab so it sticks to itself. The part that sticks to the page is made of a self adhesive that has the ability to be removed and repositioned as needed, but is strong enough to stay in place during its use as you flip through pages that have the tabs on them.
The printable tabs are available in two sizes - 1 1/4" & 1 3/4". I chose the larger as it was going to work better for my needs. If color is not your thing, they do have plain white available. The plain white ones may work for you if you want to create the colored backgrounds you want for your tabs.
Avery has some downloadable templates for you to use & I chose to download the WORD version. As it turned out the template was a joke and I could not get my text laid out like I wanted so I created my own template in WORD. It is not that difficult to make your own label template if you, but I had to use some tricks to get it like I wanted.
Avery does also have a service that will allow you to design & print what you want right from their website, but for reasons of my own, I did not use that service, so you do have this option.
Avery has only one color combination for their set of printable tabs & although nice, it would be great to have a more colorful selection. Despite the strange colors available, the printable tabs did a fantastic job of helping me access the pages in my small notebook. I bought mine at $7.71 for a package of 80 (20 tabs / sheet) I saw today they have them priced for $6.42 for the same size.
I have included a photo of one of the spiral notebooks that I used these printable tabs on.
