These first ones are a type of shibori called Nui Shibori (stitch resist dyeing).  This is a simple running stitch used on the cloth, then pulled tight to gather the cloth.  Each thread is then secured by knotting before being dyed. It’s a bit more time consuming but allows for control of the pattern you’d like to create.

Komasu Shibori: 

Place your cotton shirt so the front and back align at the sides and sleeves are in the middle. Create a template or free hand and draw triangle shapes along the folded edges.  I use a water erasable pen as it disappears in water.  Then use a running stitch with heavy weight thread (for buttons or denim) and trace the marks.  Pull the stitches on the side without the knot till they're nice and bunched up and knot the end a couple times. Once they're all scrunched use rubber bands around the tips.  Dampen the t-shirt (you don't want it soaking wet just barely damp) and place in the Indigo vat.  I wanted a deeper shade of blue so I placed mine in for 3 minutes.  Let the dye oxidize and then I let it dry till it's just a little damp and remove the rubber bands and stitches with embroidery scissors.

Nui Shibori

Another form of Nui Shibori. This one you will create a design on paper first.  I then placed it in between the front and back of t-shirt and traced it with my water erasable pen. This time I used a running stitch but I folded the fabric while I did it as shown in the photos. I also did an individual set of stitches for each petal (or section) for when you pull the threads. Pull the threads so they're scrunched tightly, tie the knots for each section and dampen it lightly. Place in the Indigo vat for 2 - 3 minutes or until you've achieved the shade of indigo you like. After it has oxidized (when the fabric is removed from the indigo vat it's a greenish color, once exposed to air it turns to blue) and slightly damp, remove the stitches and rubber bands. 
 

Itajime shibori

A traditional shibori pattern but one you can’t go wrong with. You will fold the shirt in an accordion pattern (back and forth). Once you’ve created a strip you will then fold that again back and forth till it’s a big square. Bind the folds with rubber bands, dampen and place in the Indigo vat for 2-3 minutes. 

Boshi Shibori

Another traditional shibori technique called boshi shibori. This is done by binding sections of the t-shirt with rubber bands or string. You can do them all over or in different sections. Place in the Indigo vat and follow the previous steps...
