I hot glued on the leaves and the finished rose. I wanted to make cream felt roses, but all we have in town is a Walmart and their felt selection is limited and not high quality..no cream. So I found the Warm and Natural in the fabric section. *lightbulb*. I got a 1/2 yard for $3.49 plus tax. It is 90" wide so cutting it into 4 inch squares, you could make 88 roses for that $3.49! I also got the jute twine there, but in the hardware department. It is $1.97 for a regular roll..and in the craft department it is a lot more..probably because it is hemp there and meant for jewelry. I don't care if it is itchy jute twine when I am using it for crafts!
When you get towards the end, I use a bit more hot glue and flare the petals out a bit by attaching them at an angle to the rest of the rose.
Keep the bottom edges of the rose flat.
