My mega project from last year: Making a dress with NeoPixel LEDs! Combining my sewing hobby with a RaspberryPi and LED strips.
Each layer exists out of:
First cut all coloured strips of the organza and hemmed them with silver thread. Using a hemming foot on my old sixties sewing machine. That is 6 x 7,5 meters of hemming!
Then cut the tule strips. 6 x 5 meter. 25cm wide.
and 6 x circle skirt 25 wide. Diameter of 75cm. Inner circle diameter of 25cm. For my taille circumference is 76cm.
76 / pi = 24.2cm
The outer circumference becomes
75 * pi = 235cm
Then attached the coloured organza strips to the tule strip. Ruffling them up along the way. Same as the tule strip to the circle skirt.
I cut a 15 cm opening in the circle skirts so I can slip it over my hips.
Hip circumference is 105 cm. So
105-76 = 29 Needing a cut of
29/2 = 14.5cm.
The I sewed them all together at the top.
In total the dress has 4 layers on top of the petticoat. I also added one lining layer underneath the petty coat.
From bottom to top:
|layer||circle skirt||length||color||circ waist||diameter||radius|
Hemmed everything with pink thread and a plastic (fishing) thread. To make the fabric get a firmer wave at the bottom.
Because I was afraid the Led lights won’t last all evening (or I didn’t have faith it would work out at all.. ) I installed some simple lights in the petticoat. It was around Christmas time so a lot of simple cheap led lights on batteries could be found in the store. I used 3 strings of white led lights and sewn them in the dress. Already a beautiful effect! The small battery packs hang in little sacks sewn to the waste underneath the petticoat layers.
The top is made from lining, tule and organza fabric. Desing based on a pattern I found from another dress and changed to my own sizes and likening.
The top 4 layers from the dress are sewn to the top with a pink band in the middle.
The petticoat is separate and has its own closure.
Decoration exists out of roses I made from left over pieces of organza fabric. I also found some white glitter leaves in the christmas decoration in the sale. All sew on by hand.
Verbruik: 2Amp per meter when fully lit. 1 when programmed. 0.5 when programmed less bright. 30 LEDs: 9 Watts (about 1.8 Amps at 5 Volts).
