I started out by creating divider cards for each letter of the alphabet using a 6" x 4 1/4" piece of white cardstock. I added a 2" piece of patterned paper at the top and then adhered a Scrabble tile to the card for a divider tab.
I chose my patterned papers simply by thumbing through my scrap bin for pieces that could be cut to 6" x 2". I placed the Scrabble tiles so they would be staggered in the file, thus easier to see and flip through.
I really like having this cutting mat on my craft table because it makes it so easy to line things up quickly. Here's a look at all 26 cards.
