Flower help requested for O’Keeffe art project

Hello Parents!
Next month, the children will begin one of their favorite art studies with our Georgia O’Keeffe flower paintings!
During lesson time, the guide will keep a large vase filled with flowers on a table. The children are invited to come and to paint a flower of their choosing–just like Georgia O’Keeffe! We ask that parents donate the flowers each week. The HEB $4 bouquets are usually perfect because they provide just enough flowers for all the classes to share.
I have created a sign up for the flowers at www.SignUpGenius.com/go/10C0B45A8AC28A4FE3-okeeffe1 
Thank you so much for your help and your donations! The children love this project!
