Step 1: Grab an old t-shirt - ones without a side seam are best. You also need a decent area without graphics as the print will make the yarn not curl at the end.
Step 2: Cut off the bottom hem and across the t-shirt below the armpits ( or far enough down to remove any print)
Step 3: You should now have a tube of fabric. With the closed edges top and bottom, cut strips, around 1 inch wide from the bottom to the top. Leave a 1 inch margin at the top.
Step 4: To create a continuous loop of yarn you now need to join up the loops of fabric. Insert your arm (or someone elses arm) through the top of the fabric to seperate the 2 layers. Make a cut from the right side of the top of the first strip on one side to the right side of the bottom of the second strip on the other side. (see dotted line in picture below)
Step 5: Once finished you should end up with one long line of fabric.
Step 6: To create the curled around yarn that can be used. Hold the first part of the fabric between your hands with a 10 inch gap and give the fabric a tug, then move along the fabric with your hands giving a tug every 10 inches or so.
Step 7: Roll in to a ball to use in a project
This was my first attempt at this and it was really easy - now on the hunt for some colourful t-shirts !!!!
