This is honestly soooo easy. All you require is a glue gun and these materials.
I used a wooden garden stick but you can also use a stick from outside for a rustic look! The strip of fabric can be any length you want, depending on how "full" you want your flower. My strip in this example was about a yard long.
Start by hot gluing your strip of fabric to the stick. You'll want to make sure you have about an inch of fabric sticking above the stick. Then wrap the fabric around the stick and add a dab of glue to secure. Be very careful when gluing because it's tricky not to burn your fingers! (trust me, I have blisters to prove it!)
