I also want to come up with a little slogan, as a few books mention. 'Cute, quirky and beautiful' is my tag line of my shop currently - but a lot of shops would describe there work like that. I thought about my sweet shop style bags and was inspired by a customers tweet "Chose myself a little treat from Catkin_Boutique" ;
A sweet treat from the Catkin Boutique! It sort of rhymes :)
