We were so happy when we walked into Hobby Lobby we bought everything for the wedding there we possiblly could as it was all 50% off.
They had a wonderful selection of realistic flowers. We actually found pre made bouquets of cala lillies that were VERY real looking. The prices were great too.
I bought lots of fake flowers and decor when they are on sale for 50% off. They go on sale about every 3 weeks. The flowers made a nice addition to the real ones I also purchased through a different vendor.
