Step 1: Get all you materials together. You'll need some craft foam (choose a colour that either matches or will disappear behind the sequins - black or white is best), sequin tape, 2 matching tassels, glue gun, glue, good scissors, circle template (or coffee mug), tweezers, scalpel and "thread cutters"(easier to cut in small areas).
Step 2: Draw your circle using the template. You'll want to measure your nipple (embarrasing, I know) and then draw a circle about 1 to 2 cm bigger than that. I used a coffee mug for this tassel design so they'd be a bigger design. Normally I use an architect's circle template. You can also make a heartshape template by drawing two circles touching and then make the point.
Step 3: Cut the circles out. You'll need good scissors - I actually use fabric scissors. Don't worry, the foam doesn't harm your good fabric scissors like paper does. It's soft enough.
Step 4: Cut a "piece of the pie" out of the circle. You do this so when you fold the circles together they create a cone shape that snuggly "hugs" your boobie.
Step 5: Using your glue gun, run a small bead of glue along one side of the "piece of pie".
Step 6: "Fold" together the two edges of the "pie" and hold to glue together. You will have to hold it for about a minute to keep the edges from pulling apart before the glue sets. Don't worry about glue globs - they will be hidden by the sequins.
Now you've got your nipple pasties! It's time to decorate.
Step 7: Sequin time! Start by running a bead of glue around the edge of the circle. Quickly get your sequin "tape" and start glueing it bit by bit around the circle.
Then start to "spiral" towards the center, making sure not to leave a gap between rows. Once you get to the middle and finish, use the thread cutters to get a clean cut. Take the last sequin (which will probably fall off when you cut it) and glue that separately in the middle.
Then do the other one, but be sure to spiral in the opposite direction so they mirror each other.
Step 8: Tassel Time! You'll need your tassels, a scalpel and the tweezers.
With the scalpel, cut a small slit in the point of the cone. Make sure you go right through to the other side.
Step 9: Grab hold of the end of the tassel with your tweezers, and from the sequin side inwards, push the end of the tassel through the slit you just made. Pull out your tweezers without pulling out the end of the tassel (it's a bit tricky at first, but you'll get the hang of it after a few tries). Pull the tassel through so the knot of the tassel falls at the edge of the circle of the pasty.
Step 10: Using a massive dob of glue, glue down the edge of the tassel to the inside of the cone.
Step 11: Using a bit of felt, cover the glue spot to make it look pretty and it's also soft on your poor nipple.
From these simple steps you can make any shape, colour, etc!
