Grandma's teapot

This is the teapot I'm making for my Grandma's birthday. It hasn't been fired yet - what you see is the underglaze applied with a brush and glaze pens. I've never tried this technique before so I'm crossing my fingers that it will work - Grandma's birthday is just around the corner and there's no time to make another pot! I'm hopeful that once the clear glaze is applied on top these colours will really pop.
