You will need:
a sturdy piece of cardboard, at least 7x7 in.
*optional- another 7x7 piece of cardboard
some screen or felt, at least 6x6 in. any sort of material that you can easily get an earring through, and be tough enough. Old rusty wire screen would give a cool look.
paint (i used yellow for the sunflower, but it can be any color)
sharpie (i used brown)
a needle, or something to punch a small hole in the cardboard
either a compass, or some circular object to use as a pattern (i used a sherbert lid)
Step 1: Trace a Circle
Step 2: Draw the Petals and Cut It Out
I found it easier to cut all the petals on one side first, then the other.
You might be left with some little tufts in the corners; either pick them out or cut them away carefully.
My sunflower came out a bit short on the sides because my cardboard wasn't quite big enough. Make sure yours is big enough if you don't want this to happen!
Step 3: Cut Out the Center
To make a cut, first just score along the circle; don't try and go all at once. Just keep making progressively deeper passes, and don't get into a hurry. Also you will want some kind of tough/expendable surface to cut on.
If you end up with rough bits from the cut, take the cutter and CAREFULLY trim them off, like you are whittling wood.
At this point, you could find an angle that it hangs nicely from, and make a hole at the hang point.
Step 4: Paint Your Flower
Give your flower several coats of paint, and plenty of drying time between each coat. Because i started off with bare cardboard, it took me quite a few coats to get the color i wanted without the brown cardboard showing through. If you were to give it a base coat in white it probably would take less.
To keep your petals looking neat and semi-realistic, make sure to stroke from the outside towards the inside of the circle each time; dont just slop it on in any direction. Don't forget to give the back a coat or two!
Because i only had yellow paint in acrylics, i used some watercolors to create some shadows and keep it from looking too flat.
Once all your paint has dried, outline your petals in sharpie. (i used brown because i thought it looked nicer.)
Step 5: Add the Backing
Take enough screen or felt to cover the hole with some overlap, and trim it so that none shows over the edge of the petals.
Put the screen to the side, and lay down a line of glue around the hole. Don't get right up on it, leave a small space.
Put the screen down over the hole, and take your finger and spread the glue away from the hole. As you work, make sure the screen stays taut over the the gap. Pull it to the edge if its getting too wrinkly.
At this point, you could take another piece of cardboard, cut a slightly larger hole out of it, and trim the outer bit so that it doesnt show over the petals. Lay that down over the screen in the back and let dry. I was too lazy to do this, but it would help keep the screen in place.
