The 5 pack of EL wire I ordered just got here yesterday and I was actually giving the other 4 out to my crew so our packs can be dope AF. EL wire looks a lot better in low light situations since it isn't a strip of lights but rather the entire strand is lit so it isn't as annoying to others o_O
I haven't secured mine yet but either pins or tape will be my go to.
The El Wire I used: https://www.amazon.com/dp/B005Q5WVBU/ref=cm_sw_r_other_apa_i_5CTYDbD9JHQQ7
String: https://www.amazon.com/dp/B000IGEBSS/ref=cm_sw_r_other_apa_i_eFTYDb58P80HW
The El Wire worked pretty well, but when I put it on flashing they flashed at different speeds. Though it did have a neat effect.
Good luck!
EL wire and LED squishy rings!
El-Wire is the standard. It's the light up string stuff you've probably seen before. You can get it very cheap on Amazon and it's easy to hot glue onto anything. Two AA batteries will last you nearly the entire weekend.
