This DIY floral arrangement was such a charming and easy way to celebrate a milestone birthday! I used a waterproof bag inspired by the iconic Chanel No. 5 bottle—except this one featured the birthday girl’s number (how fun is that?). It comes in tons of milestone numbers—30, 40, 50, 60, and even some random ones too—so it’s perfect for gifting or party decor. Just pop in a few fresh flowers and you’ve got a stylish, personalized arrangement that feels high-end but totally doable.
