I can't believe I didn't find them sooner.
After my last florist dropped the ball, I panicked and found My Little Posy on good ol' Yelp. I had a photo shoot and needed a last minute flower crown made. I tried making it myself and it took 3 hours and looked like a 5 year old made it. My hands felt like they had arthritis after. No way was I going to DIY again.
My Little Posy asked questions that my last florist didn't even ask: 1. What time is the photoshoot 2. What colors are you wearing 3. How are you wearing your hair 4. What size is your head etc. They got my crown made on time for $75 (and my last florist was charging $90). My flower crown was better than I imagined, lasted longer than I expected considering it was super hot and didn't have a water source. I would recommend My Little Posy hands down due to their superior service, prices, how they listen and ask questions, quality of flowers, and the team really takes care of you.
Go to the flower crown masters! They school everyone on flower crowns and slay all the florists in Phoenix/Scottsdale!
