A few months ago I searched for a wool hat with flowers to buy for HL. When I couldn't find one I bought a plain wool hat from Wal-Mart and added felted flowers.
I used a good quality felt that had a wool fiber content, soaked it in very hot water, & dried it in the dryer. The die was used to cut five graduated sizes of flowers. I used a running stitch to gather a small circle in the center of each flower, then stacked them together and added the button from my button stash. I spent a lot less time making the flowers than I had searching for a hat with flowers.
