The regular size bow tuck is 13" wide, 11" tall, and 5" deep. The mini is a great size for a purse. The regular size is the one you want if you are the person who has every thing but the kitchen sink in her purse (me).
I found this pattern very easy once I read it through a couple of times. I'm patterned challenged, but I found this one pretty easy.
Watch out though, the bow tucks are addicting. I'm working on number 13.
