Simplified Snow Dyeing (NO soda ash required)!
1. Washed and dried white or natural fabric. I LOVE working with un-dyed organic bamboo french terry fabric. There's a wonderful Canadian supplier called Kindrel that I get all these lovely fabrics from. It's only about $11 (US) a yard for the heavy stuff, and it's worth every penny! I've also dyed cotton (up-cycling old t-shirts) and it works just as well.
2. One-step tie dye kit. Any craft store has these kits, and they're pretty affordable if you catch them on sale. Don't get the professional dyes, because those require the soda ash pre-treatment.
3. A plastic bucket that has a lid.
4. Mesh or metal rack to keep the fabric out of the melted sow puddle. I used a rack from the warming drawer in my stove, and a cookie cooling rack. I have also seen people use window screens, etc. It doesn't seem to matter much.
Place your rack in the plastic bucket. Scrunch up your fabric and place it on top of the rack. Make sure no ends are falling through or are hanging off the edges.
Now for the dye, I tried 2 different methods and both worked. The first method I used was to mix the dyes with half as much water as called for in the instructions (I didn't want the dye to dilute too much once poured on the snow). Lauren squirted the dye onto the snow in blobs of colour. I'm sure you can get very creative with this step.
The other method we tried was to just directly sprinkle the dye powder onto the snow. This method gave a result that had more concentrated sections of colour, with some very dark and very light spots. The liquid method had a more uniform colour blending.
Have fun covering the snow with colours! I found that using 2 colours gave plenty of variation in the end result.
