Tie-dying is a tried-and-true camp craft.
Making a great tie-dyed shirt
Top tips for a great tie-dye experience?
Mix the soda ash and dye solutions ahead of time. Store mixed dyes in the refrigerator so they don’t lose strength.
Make sure the rubber bands are on super tight; the tighter they are the better the shirt will come out.
Make sure to wear rubber gloves.
Pick colors that will look good together – like turquoise, navy blue, crimson, etc. If you want high contrast like yellow and purple, be sure to do the colors at separate times so the purple and yellow cannot mix! Maybe you can do the first (lighter) color one day and the second color the following morning.
Rinse project after dyeing with warm water, followed by a cool water rinse.
