I really should have documented the entirety of the project. Unfortunately I only have the final product.

I purchased a packet of Dylon fabric dye, and use a dark purple colour. I filled a bucket with 6L of wwater, added 5 table spoon’s of salt and added the sachet. i then proceeded to tie hair-ties (i have no rubberbands!!) and tied them around evenly apart, in a messy manner. i left it in the bucket for a couple of hours, drained the bucket, and sprayed the bucket with clean water! i let the skirt soak for another hours and then repeated a rinse.
For this project I used a cheap, cotton white skirt. The beauty of tie dye is that you can basically use all the rags/crap from around the house. Next time, I may try and make head bands. Bonne chance mes enfants!
