Here in AZ the summers are so hot neosporin in the car 1st Aid kit doesnt survive long so instead of buying cheap single use neosporin packets I started making these. I got this from Brian's backpacking blog. This got me started thinking... What else can you do with this kind of one use kit I carry sewing kits in everything, purse, cars etc. When 911 hit and we couldn't carry scissors on the plane I started carrying sewing kits in a medicine bottle. Which is ok but still bulky. This guy does sewing kits for backpacking with straws and it doubles as a bobber for fishing. He pre=threads a needle for clothing and a needle with waxed thread for sewing gear. DIY: Drinking Straw Sewing Kit What other creative ideas do you have for using straws for 1 use kits, sewing, fire, medical?
