The second pic is a chocolate bouquet I tried my hand at. (It looked so much better in my head!) I used a cardboard gift box for the base, wrapped some red and white "happy birthday" ribbon around it and added floral foam to the box. I found some heart shaped chocolates wrapped in red foil, and also bought some lindt balls wrapped in red too. I cut out some flower shaped pieces of black cardboard and stuck the heart chocolates to them. For the lindt balls I used red cellophane and black tissue paper squares to make "petals" around the chocolate. I then attached wooden skewers to the chocolates and poked them into the base as well as the "18" thingy that I'd bought. Then I just tore up some red and white tissue paper and screwed it up to cover the foam base. Although this pic doesn't show it, I then wrapped the whole thing in clear cellophane and added some of the matching ribbon to it.
The third pic is of a balloon bouquet, once again not as pretty as in my head! I bought a black and white gift bag and added more floral foam to it. I put balloon sticks into the foam and added some 18th birthday balloons.
