Here is a picture of the t-shirt headband we made (a couple of posts ago I talked about it). I had a request from Jamie for it. :) I'm not going to write a tutorial for it, but I'll try and do my best at explaining what we did.
For the other strip for the flower we used a piece of t-shirt that was 3 inches by 24 inches. We held the ends and twisted it so that when you put the ends together it curled around itself. Then we just started gluing with a hot glue gun around and around until your flower was formed. Then, we glued it to the sewn part of our headband.
Super easy! (I hope my directions made sense.) :) You could make these with any color t-shirt you wanted, or just make the flower and hook it to a clip. Happy crafting!
