The advantage of having a mother that own a flower shop is that the shop is filled with fun stuff to decorate the house, like vases and pottery. And I can practice with drawing them!
I just choose some objects, put them on display nicely and draw them. I focus on a few things, shadow, drop shadow and the reflection of light in the glass.
Still lifes done with paint, pastels or conté chalk.
You will get dirty hand anyhow, so I don’t even try to keep them clean and just wipe across the paper.
