If you'd like to see how it's done, I'll show you! Start by choosing a bunch of random fabrics and cutting strips of varying widths. Mine ranged from .5" to maybe 3".
After cutting your papers into squares, draw a line on the diagonal from corner to corner.
Sew a quarter inch seam allowance right through the paper. Use a small stitch length so that your paper will perforate well and you can more easily pull it off later.
Press the strip open.
Repeat with another strip on the other side of the white strip.
Add another strip to either side of those.
Cut the top and right sides off.
Rotate your square and repeat.
