I am not sure about neon fabric but I can tell you a source for neon cording. Home Depot sells bright neon cording in orange, yellow and green. And it is much cheaper than buying it at a fabric store or even Walmart. DD wanted a drawstring bag for her trip to New Oleans. I used denim and got some bright neon green cording at Home Depot for about $3.00. DD loved it!! I had enough for her bag and now DH has a good amount of cording left for what ever he may need.
