5x red, blue, pink, purple, yellow felt (you may need more or less depending on the size of your pillow & the size you draw your heart. Wendy needed five sheets for her 14 x 14 ruffled heart pillow). You can get felt sheets from any fabric store, craft store, some supermarkets/drugstores.
Approx 3-5 yards of fabric for both the pillow case + all the petals
Hot glue gun + hot glue sticks
Needle and thread OR fabric glue for a "no sew" pillow case
