This was another school assignment. I’m not sure for what could this be useful, as long as you cannot wash the fabric without it loosing its shape, but it was a fun experiment nonetheless. I used some stones my friend from work gave me. She brought them from the seaside in Greece. I think that the fact that they are so calcareous helps the fabric keep its shape, some of the chalk like dust form the stones staying in the fabric.
I tied the stones in the fabric, I put the fabric in boiling water and I let it boil for an hour with two spoons of turmeric and 250 gr of vinegar. I let the fabric sit in the water for 2 days, then I let it dry without taking out the stones. Actually, I let the stones there for weeks, because I wasn’t decided if I want them out or not, but I think that just letting the fabric with the stones in it till it is perfectly dry should be enough. The fabric keeps its shape perfectly and the colors are quite pretty.
