You'll find a pretty eclectic selection of cutters in this category. All the holiday themed cutters end up in here, so you'll see things for Halloween, Christmas, Valentines Day, etc. but you'll also find cutters great for events in here. Birthdays, bachelorette parties, recitals, graduation, and so on.
For 'Birthday' I pretty much have included any cutters that I find people frequently order for themed birthday parties, so you'll find things like Monster High, Ninja Turtles, and Comic Book logos in here as well.
