  1. Gather the materials and tools shown.
    • Gather the materials and tools shown.

    • Print the template and circuit diagram file found at the bottom of this guide if you think you need templates for the felt and cardboard rectangles pictured.

  2. Cut a small rectangular piece of cardboard as pictured (about 1"x4") and stick a piece of double sided foam tape to the middle of it. If you don't have foam tape, a masking tape loop should work but may need to be refreshed as you create all three jewels. Stick a single led to the foam tape by the legs (about 1/8") from the bottom of the LED bulb. Bend/fold both of the edges of the cardboard as shown in photo 2. You will use this setup to  hold each LED upside down within a mold during the hot glue application and hardening. These jewel LEDs work best when the LED bulb is COMPLETELY encased in hot glue. The most likely spot this may NOT occur is at the tip. To avoid this, make sure that when you position the cardboard/foam tape/LED combo in the mold, that the tip of the LED bulb does NOT touch the bottom. If it does, pull the LED off of the tape and reposition.

  3. Using clear hot glue and a hot glue gun, squirt liquified hot glue into the mold until the glue covers the entire bulb. If your LED positioning got jostled around during the mold-filling, now's the time to adjust while the glue is still liquified. Allow the glue to cool and harden before removing from the mold. If you wish to accelerate this process, simply put the mold tray in the refrigerator.  When you no longer feel any heat conducting through the mold tray from below, remove your uncut gem by pushing up on the underside of the mold.

    • NOTE: Trying to pull the LED out of the mold by the legs may break or damage the LED. This is not the preferred way of removing it from the mold. Push UP from the underside of the mold until you feel the shape release. THEN pull it out.

  4. Attach a new LED to the cardboard/tape and make/remove a second jewel using the same process that you did for the first one.

  6. Use a scissors to remove any weird excess making the jewel edges nice straight and enabling the jewels to lay flat! Notice that, for each LED, there is a short leg and a longer leg. Bend the legs of each outward in opposite directions and note which are the short and which are the long. You will need to orient the LED jewels on the felt with all short legs on one side and all long legs on the opposite side.

  8. Put a dab of hot glue on the round bottom of the first LED and stick it in place to the felt. Note the position of the short LED leg and the long leg. Repeat this process for the remaining two LED jewels taking care to keep all short LED legs on one side of the felt and all the long legs on the opposite side.

  9. Cut a piece of Maker Tape that it approximately 2" long. Use photo 2 as a reference and stick half of the length of the Maker Tape segment to the under side of one of the LED legs (this puts the sticky side up). Then fold the remaining half back over the top of the first half. The result should be that the LED leg is now sandwiched between Maker Tape. Cut 5 more pieces of Maker Tape of the same length and repeat this process for each on the remaining 5 LED legs.
