i've had my eye on this good tie dye kit for a while, and jumped on the chance when it was on sale--
we used this exact kit, which i would highly recommend. especially if you buy if for 50% off, or use a 40% off coupon.
the kits uses the good dyes, and soda ash to fix the colors. i also learned that using 100% cotton is key and makes a huge difference. i don't even know what kind of junk we used in the past but it made this kit look completely rock star. johnny, being johnny, researched and WATCHED THE DVD THAT CAME WITH THE KIT MULTIPLE TIMES before we could start the adventure as a family. but let me tell you, the research paid off and they all came out amazing! and nobody burnt any of their skin off! and the kids can tell you the names and differences between all the different patterns! and now we can all go out in public completely matching in tie dye and make complete strangers uncomfortable! it's perfect.
(of course, being in your underwear while doing tie dye, like joey is demonstrating, is completely key to the process as well)
you should totally try it.
