Hi,[no worries!]
Great idea! Forgive me, I really couldn’t stick to 4.

1) Poppies! I’m currently obsessed with Poppies – possibly due to the amazing tea set I inherited from my Grandmother. So I’d definitely go with poppy themed invitations, these were my favourite of many.
* Tip - Make sure you get matching thank you cards at the same time so you can start sending them out as soon as the early bird gifts arrive.
I would complement the poppy theme with a few more “poppy” items in addition to the centerpieces and flowers.
Guest book:

OR I love the idea of creating a poster sized invitation to have your guests sign.
Place cards:

A matching tie for the groom:

2) One signature item of clothing to really make the bridal ensemble pop and accent your theme.
Fascinator:

Necklace:

Wrap:

3) And now for some fun! I did homemade cupcakes for my own wedding instead of cake. Perhaps for a DIY favour, you could combine the recipe for your wedding cupcakes on a snazzy recipe card, with a small canning jar full of the pre-mixed dry ingredients. i.e. Just add milk, eggs etc for your own “eat at home” cupcakes!

4) Lastly, we can't forget about bridesmaid gifts. I like the fact that you can get wristlets by babycakesboutique in several different Amy Butler fabrics so your bridesmaids never have to show up to a party with the same purse after the wedding.
