Our Chippa soft goods are made with hand block-printed cotton, a technique that has been passed down from generation to generation. The beautiful patterns on the fabrics are created using wooden blocks. These blocks are hand-carved using basic tools & manual drawings. Once the blocks are ready they are dipped in natural dyes & the color patterns are transferred onto organic cotton. Each design involved multiple blocks & dyes which have to be carefully aligned to create a beautiful and colorful final product.
