8-bit Flower Bouquets. We received one, however, and found out the design was one-sided and guests unlucky enough to sit behind it would not be able to enjoy it. After getting the one, we thought about how we could re-create it ourselves, using foam core, but a solid idea never surfaced. I'm kind of glad I didn't see this Instructable on making pixel centerpieces until after our reception (I totally would have attempted it, but I think it may have been a little too involved for me).
I saw this Piranha Plant centerpiece originally referenced on Offbeatbride.com and liked it, but thought I could improve on the design.
I started with large styrofoam balls and painted them with two coats of Mod Podge (apparently my favorite adhesive for wedding-crafting :) to help seal the styrofoam so I could get more even paint coverage with fewer coats.
Husband did his part by cutting out the mouths with the largest knife in our kitchen.
I used the end of my paintbrush for the smaller circles and voila! Perfect spots!
Originally, I had planned on putting them in terra cotta pots, painted green. Leaves were added using pipe cleaners instead of felt.
Our plans changed, however, when our guest list grew so much that we had to add extra tables and our cat broke one of our pots. I was too lazy to make any more, so we ended up planting our piranha plants in real plants bought from our grocery store for $2-$4/plant. We classed the pot up a bit with a bow made from tulle. Bonus, we have some greenery for the balcony at our apartment!
