The base of the roses begin with a circle. In this case, I used a 2 in circle but you can adjust the size of the rose based on the size of the circle you use.
Adhere the bottom with a strong adhesive. I used Stampin' Up! sticky strip to secure mine.
I hope this helps! I suspect you could use these instructions with other kinds of paper and get the same results....crepe streamers, tissue paper and maybe even some fabrics.....
Have a good afternoon!
