This piece is accordion folded and tied.
The piece above is made by wrapping the fabric around whiffle balls, believe it or not!
This is another one made by folding and using rubber bands to secure the folds.
This was a stitched resist where I used a running stitch in a spiral design.
Here's a Linen/Cotton shirt folded and dyed twice,
once with horizontal folds, then again with vertical folds.
