These daisies would be super easy to make. You just need a daisy cutter (doesn't have to be a plunger type). Roll out white fondant, cut, then use a small balling tool (pearl pin head would work) and draw down each petal from the centre to the tip on a foam mat. Allow to dry on some dimpled foam to keep some shape, then glue a little ball of yellow fondant in the centre. It's time consuming but easy.
