For some inspiration you could start with a look at the Red Poppy group on Flickr, mostly real flowers rather than designs or art/ crafts. But, there are different shades of red with poppies, some are pink and white too. You might decide to make a batch of flowers in all shades of colour.
Maggie’s Crochet has one of my favourite crochet poppies. Includes video instructions for right or left handers. She calls it a button poppy because you pin it on, or wear it in a buttonhole, traditionally. But, you could use a shiny black button in the middle. I think that would be especially pretty. Something a little sparkly would set it off nicely.
Here are her free instructions:
