I've included a tree pattern that fits 8" or 6" embroidery hoops, or you can make your own shape.
Step 1: Materials
- Embroidery hoop (8" or 6")
- Green felt
- Star shaped button
- Embroidery floss
- Embroidery needle
- Round/needle nose small pliers
- 8 LEDS (5mm for an 8" hoop, 3mm for a 6" hoop)
- LilyPad Coin Cell Battery Holder (if this is too big for the 6" hoop pattern, a sewable battery holder will also work)
- 3V 20mm coin cell battery
- LilyPad Slide Switch
- Conductive thread
- Glue gun
Step 2: Prepare Tree Design
Cut out a tree shape from felt and center it on the fabric, pin in place. Design your own tree or print the PDF pattern I attached.
Step 3: Sew Applique
Futuregirl Craft Blog has a great tutorial on the blanket stitch if you are new to it.
Step 4: Attach LEDs
Arrange the LEDs with the longer leg (+) facing the top of the hoop, and shorter leg (-) facing the bottom. Poke an LED through the holes in a star button at the top, with the + leg on the right side.
If you don't have a button, you can use yellow felt for the star.
Step 5: Prep LEDs for Sewing
Once all the LEDs are bent, use the pliers to spiral the legs into loops for sewing.
Step 6: Sew + Power Lines
Using a running stitch, travel up the length of the tree to the star and sew to the loop. Wrap the thread tightly around the loop a few times for a secure connection and knot. Trim excess thread.
With a new piece of conductive thread, loop around a section of your 'power' line/running stitch near the top loops on your rows of LEDs. Carefully sew each LED loop to connect to each other across the row. Do not let your thread touch the bottom loops. When you get to the last loop in the row, knot your thread and trip the tail.
Step 7: Sew Switch and - Power Lines.
With a new piece of thread, sew the other side of the switch and repeat the process used for the power lines (a running stitch up the side of the tree to the star). Make sure to leave some space between the top loops of the LEDs so no short circuits occur.
Sew the bottom loops of the LEDs to the line.
Once all LEDs are sewn, insert the battery in the holder and test it out.
Step 8: Finishing Touches
Flip the switch and hang on the wall using a thumbtack or nail (make sure not to let any metal on the hanger touch your conductive thread). Enjoy!
