Itajime is a Japanese word meaning Ita=fold- Jime=clamp.
This technique is bold and graphic an exciting study of positive and negative space, and the design possibilities are endless.
The cloth is first folded using simple accordion pleating. This rectangular strip is then again fan-folded into square or triangle shapes.
This bundle of cloth is then sandwiched between two pieces of shaped wood or other solid forms, which are held in place with stings and clamps. These shapes prevent the dye in the vat from penetrating the fabric that they cover.
This vat dye process then can be repeated for a second or third colour by just changing the position of the forms.
