Initially, I planned on using as many LEDs as possible, starting from within the rose. The LEDs would light up when the rose was unfurled, but would turn off when rolled up. I thought this was due to the conductive thread touching itself when rolled up, so I decided to only use a couple LEDs in the outer petals. I used sewing needles to connect the circuit when I was testing to make sure the circuit worked before I finalized everything.
