Supplies: Go to Michael's and hit up the fake flower department. There you will find fabric covered "stems" (wire covered in fabric) in packs of 12. I bought 4 of these but only ended up using 3. I also bought a high heat glue gun and several packages of glue sticks. You're going to need a lot of hot glue. Then find a book either from your personal collection or from Goodwill or a garage sale that you don't mind destroying. You're going to make "petals" from these book pages, in varying sizes, and you're going to make a lot of them. I pre-cut all my petals to make the actual assembly go faster. D and I sat around after dinner for a few nights watching Netflix and cutting out paper flower petals. I did 6 sizes, although all cuts were inexact because I am lazy and I figured flower petals come in all shapes and sizes. It was easy peasy.
Assembly: Start with your stem
Grab one of the smallest size petals and put a line of hot glue along the bottom
Wrap it around the stem until it's a little cone of paper. This is the center of your flower.
Grab a second petal, add a line of hot glue around the base of it, and wrap it around the first petal. You want to make sure that you rotate the stem and glue the petals on in a swirl pattern, to mimic what an actual flower looks like.
After about 4-5 of the smallest size petals, move on to the next size up.
Once you get a little further along, you want to start bending the petals out slightly, so that they look like a rose in bloom.
Tips: The first flower you make will take seven million years. Do not despair. You'll get faster as you get the hang of it, and we ended up averaging about 20-30 minutes per flower. Also, you're going to burn the shit out of yourself on the hot glue. Don't worry, you'll regain sensation in your fingertips after a day or two. Also, Google around for coupons to Michael's. They always have some kind of deal going on, and they even take e-versions of coupons if you have a smart phone.
