Should I colour fast these ?

I made these for my sister's 80th Birthday in her favourite colour. I'm not sure if the red colour will run into the white. Should I treat them before gifting them to her. If so, how do I do that. They are crochet with Bendigo Woolen Mills 8ply cotton.
There is a set of 6 place mats, 6 coasters, 3 tea towels & a pair of writs warmers/fingerless gloves.

Thanks so much for any advice and help.
Cheers
