I love doing these because they are so easy! I've used them alot... on T's and on this clutch:
Here's how to do them.
I cut my fabric in a 1 inch wide and 12 inch long strip. Pull the strip so that it rolls up into itself... I used jersey for this rose, but you could use regular T shirt material as long as it stretches!!
Now, hold one end, and stretching it as you go, wrap it fairly tight around your pointer and index fingers.
Tuck the end into the middle and place thumb on it to hold.
Keep going, secure the center, and for the last stitch, add your embellishment. I used a little pearl, but you could use any beads or buttons, etc...sorry I forgot a pic of that! Tie off the bottom securely. If you are gonna mount them on a hair clip like I did for this tutorial, then I recommend cutting a little cirle of felt and hot gluing it the bottom of your rose.
I put a thin bead of hot glue to the top of my big bobby pin and pressed my rose onto it.. I added two to each one of mine... and that's it!! Pretty:)
