I think there should be class on tie dying that's teaches stuff like: How to tie dye Basic patterns Moderate patterns Best place to buy supplies How to dye other than just t-shirts Mixing charts Just a thought.
I'd like to see others input as well. I've done some teeshirts and 2 set's of flannel bedsheets. The only pattern I've done is the old school tie but I often think I should try something really cool. Not spam but, this place is an excellent place for supplies. Their quality is excellent and reasonable prices. http://www.dharmatrading.com/
Tie dyes are great. I want to learn batik and silk screening. Plain tie dye gets boring after awhile.
I love tie dying. I've made a few shirts and a whole bedset. I have a fitted sheet fit over the poles on my bed frame so I sleep under a tie dye canopy. I can't wait to make more
