Fake flowers

Where did you guys get fake flowers with stems from? We just can’t get over fake flower bouquets from a florist can cause sometimes more than my dress. And I only need my 2 and 4 bridesmaids bouquets made. Since I’ve made bouquets for a friends wedding before we just decided I can do it myself. Why we didn’t think of this before I got no idea! We went to Walmart to look as well as Joann fabrics, and hobby lobby. I’ve thought of going to Michael as well. But wasn’t sure if I can buy bull flowers online. I’ve looked at Amazon but neither of us want roses. I know, unknown territory there. But we are doing roses for centerpieces. So we feel we have plenty of roses. Any other places to look either online or different stores. Please and thank you!
