Glue (I use stinky E6000, I bought a new tube with a pointy tip)
Step 1 - Gather supplies (of course, a cute bunny is helpful! ;-)
Step 2 - I cut a strip of felt 1/4" wide to line the inside of the headband. This isn't necessary, but I wanted a "finished" look and thought it might add some cushioning.
Step 3 - Cut a section of felt that's just a little bit smaller than the appliqué.
Step 4 - Glue the ribbon to the outside of the headband (I used velvet ribbon for this headband).
Step 5 - Glue the felt strip to the inside of the headband (I left an opening to reduce bulk).
Step 6 - Glue the appliqué onto the outside of the headband, positioning to desired location. I used bobby pins to help hold it in place while the glue dried.
Step 7 - Glue the felt section onto the back of the appliqué, sandwiching the headband in between the felt and the appliqué.
And you're done! Let dry! Have fun!
