OK, so this is a bit
of a no-brainer, but I just joined and figured I'd contribute something. So there!
Here comes the tutorial, ready?
Dritz covered button kit in size of your choice (I got this 3/4" in Joann)
Needle nosed pliars
Hot glue gun + glue
Fabric pen/pencil for tracing
Clip of your choice (spring, bendy, bobby pin, etc)
And helpful (albeit thoroughly confused) assistant, of course
Step 1: Ruin the flowers (this is my favorite part)
Step 2: Glue leaf to the underside of the bottom petal set
Step 3: Glue clip to leaf
Step 4: Start gluing petal sets one at a time, making sure the center holes match up
Step 5: Trace and cut out some fabric petal sets (I did 2 for this one)
Step 6: Continue adding petal sets until you're reasonably happy
Step 7: Complain about all the glue on your thumb ("#%$@&!!!")
Step 8: Cut out a circle of fabric for your center button (I used minky, but you can use whatever. Don't worry, the kits come with a template on the back.)
Step 9: Place the fabric over the white plastic mold, and stuff the button dome into the center
Step 10: Remove the hook from the button back
Step 11: Tuck the fabric into the button, put the back in place, and pop it into place with the blue plastic button back popper thing. (If you're using minky and are a wuss like me, you'll have to put the whole ensemble under a couch leg and jump on the couch.)
Step 12: Glue the button to the center of the flower...
...Tada! I even frayed the edges of the fabric for some extra funk after taking that last pic. Oh, and please excuse my finger toes!
