Bra top

  • Let’s begin by tracing the circles on the felt. Make sure this is bigger than what you want since we are going to be reshaping it.
  • Cut out the circles
  • Now cut them in half as we are going to make our shells two toned
  • Square off the edge. Think of this as making two sideways cupcakes
  • create the scallops for the top
  • glue these two pieces together. Trim off any excess
  • Fold, pinch and glue the inner part. Sometimes its easier to do it from the back side of the shell
  • Glue the shells to the top. Try the top on first to make sure you are gluing in the right spots
  • Make sure you only glue in a few areas to keep the integrity of the shells
  •  Glue on some sequins, rhinestones or sand.. whatever you want
  • Using some Gemtac glue down the sequins. This came from Michael’s for $1 a spool
  • Dip the toothpick into clear polish then pick up the sequins. This will make it a lot easier.


Take your sparkly fabric and wrap it around you like a sarong. I picked this up for $3.99 a yard at Joanns.
  • Figure out when you want the “V” to be and mark it
  • Cut the “V” and then follow with scallops to the end. By making it higher it will be easier to walk.
  • Try it on again to make any adjustments
  • Take Tulle #1 and fold it the long ways. Cut it in thirds. When you roll it out it should still be a yard.
  • Take Tulle #2 again fold it the long ways. Cut this in half.
  • This is the hardest part. But its simple if you follow the tips.
  • First apply glue to the fabric at the V section. Let it get tacky and cool a bit. Then press the tulle down into the glue. Don’t touch the glue. Use a stick or apply pressure to the surrounding area.
  • Fold the tulle over so that you make the V part full with the tulle.
  • Glue a straight line along the scallops. Again, let the glue get tacky and cool a bit before pressing the tulle down. If there are any parts that stick up just glue through the tulle from the top.
  • Use one tulle per side and the last one for the V
  • Take that last short tulle and glue it in the front V part to make it fuller
  • Now repeat with the second sized tulle. Layer this on top of the others. Work from the front to the back.
  • Do this on the other side with the other tulle. This will give you a split in the front when you keep the tulle separate from each side.
  • Finally glue the longest pieces one on each side.
  • Cut two strips of felt for the front. This will conceal the tulle, glue and make it a bit more structured
  • Apply glue to the tulle and the top of the tulle. Firmly press down the felt on both sides.
  • You can cut the top to make it easier to tie but I prefer it like this for a fuller bow knot.
