I picked out a pattern from CPC, its the Victorian Rose Doily (pdf).
Its also the same rose doily here.
I managed to make my own design for the leaf, I like it better this way.

Materials used: crochet cotton size 8 for the doily and roses, 6-strand embroidery floss for the leaves, 1.75mm steel hook.
Here's another valentine doily.
