I got a file pocket in white (it also comes in blue as shown below).
So we first divided the recipes into categories. We settled on savory, breakfast & desserts. Not surprisingly, there were about twice as many recipes in the "desserts" category. :) What can I say? We have a baker in the house. Then I just put a piece of washi tape over the tab. That way I can change out the categories without ruining the file folders if we wanted to changes things in the future.
