can you tiedye a lon-jon shirt?...or would the colors just bleed really bad because of the way its made?
If it has polyester or spandex in it it wont Dye. but is it is 100% cotton or it will certainly hold the dye. Here are some alternatives in case it is a mixed blend... http://www.dharmatrading.com/html/eng/3307-AA.shtml Good luck.
if you are wondering about the waffle weave, basic folding works fine on it. I would not bother with fancier stuff like tritik, bhandana or shibori poly blend will give you pale colors with a whitish top layer. I find it rather disheartening when I use sapphire on, say a usually mislabeled LL bean T-shirt and get "polyhaze"
