While I was working on my shibori pieces, I also did some pieces using bleach in a spray bottle. If you would want to do this, I suggest you do it outside (which I did--even though the temperature was in the 30s). You MUST HAVE good ventilation when working with bleach and anti-chlor. I thought the pieces turned out interesting. I'll be doing more of them.
This is what I started with...some string and two keys strewn onto my fabric.
I used straight bleach sprayed from a spray bottle, and this is what I got...
After I sprayed the fabric with bleach, I let it sit a little while (until the color was a bit darker than I wanted). Then I removed the objects from the fabric and put the fabric into an anti-chlor solution (for five minutes) to stop the discharge of the dye. I waited a bit too long on this particular piece. I think it turned out a little too light. What I think I'll do with it is overdye it with a color. The anti-chlor solution I used was 1 teaspoon of anti-chlor to 2 1/2 gallons of water. I rinsed the fabric in cold water after the anti-chlor bath. I followed this same procedure for all of these pieces.
This is what turned out when I used "Jet Black" fabric from Blank. The color is a beautiful rusty/reddish brown. The picture doesn't do the color justice. On this piece, I again used the keys, some jute, and three bottle caps.
On this piece, I sprayed bubble wrap with the bleach. Then I placed the fabric face down on the bubble wrap and lightly pressed the fabric into it with my gloved hands. After that, I put the fabric on the table, added some string and a glove and lightly spritzed the whole piece with the bleach. I let it sit for just a little bit before putting it into the anti-chlor solution. I like the depth in this piece.
I have lots of ideas about things I can use to make more of this unique fabric. It was great fun. Why don't you give it a try?
