Mine are sort of mismatched in that the decoration on each is different but they are the same in shape and theme. They are the Flowers ones from Emma Bridgewater that I've acquired over some years, through sales and seconds shopping etc. I love them so much that I display them on a hook display set fixed to the underside of the kitchen wall cabinets by the kettle like a sort of dresser. The really mismatched ones lurk in the cupboard for emergencies such as the need for a Really Big Mug of hot chocolate .I have a Ghostbusters mug that I got from Halloween Horror Nights pre-pandemic. It's tacky and wonderful BUT it's my personal mug. I have two sets that are plain for guests and general use. I couldn't abide having them all mismatched.
