For the no sew headband turban you'll need:
First you'll take your t-shirt and spread it out to cut. I used an old plain white t-shirt I had laying around that I used the corner of for another project. Try to use old shirts that are kind if large and stretchy fabric is better too. If the shirt is too small it won't fit over your head very well.
Then twist in the middle twice like this to make what looks like and infinity symbol.
Next is the (some) sew but no machine necessary beanie turban. Here is what you'll need:
The shirt I used was kind of like a thin sweater almost, with a large band at the bottom which I thought was perfect for a beanie. To start, I put my shirt inside out. The I took my shirt and measured it around my head keeping the side seam on the side of my head. I pulled it a little tight because I wanted it to have a snug fit. Then I marked where I wanted it but be sure to make it just a tad bigger than you want you'll need to have room to sew.
My marks are kind of hard to see. Using both marks you made draw a beanie shape and cut it out of both side of the shirt. If I makes it easier you pin both sides of the shirt together to make and even cut on both sides.
Now just take your needle and thread and sew along the line you cut out! I hand sewed this but if you wanted to you could use a machine. When you are done sewing flip it inside out and it should look like a beanie.
Next is the front detail. First, you pinch the very front bottom middle of the beanie using you pointer finger and your thumb, as shown below.
