In my opinion, Doodlebug has some of the best fonts when it comes to alphabet stickers. The playfulness of this font works for so many themes. I am glad that they offer Loopy Lou in so many different colors.
I just used these to finish a LO I'd been waiting to complete for months - the color and the shapes of the letters make them very fun to play with! The stickers hold well but are repositionable when you first apply them, which makes lining up words a lot easier. Great product!
