Israeli designers Idan Noyberg and Gal Bulka have replaced sewing-machine needles with stamps that print lines of patterns onto fabric.
Noyberg & Bulka designed the Sew-ink stamps as a way of revamping old clothes.
"The inspiration for our project began with working with our own sewing machine trying to make an interesting pattern with strings on an old T-shirt," Noyberg told Dezeen. "Then we had this idea to connect between ink and sewing machine in the most simple way, in a way that offers a new concept of sewing."

The stamp's node radius is the same size as a standard sewing-machine needle shank, so is secured onto the machine in the same way.
As the fabric is fed under the foot of the sewing machine, the stamp prints a small motif onto the garment over and over to form a linear pattern.
The patterns can be added around collars, cuffs and pockets to add details to plain garments.
The duo experimented with a series of simple shapes and more complicated designs for the stamps, and hope that users will be able to 3D-print their own versions.
Initial tests were carried out with diamond, sun and ant-shaped stamps on white shirts.
"There are unlimited options for production and a future option to print your own design shape using 3D printing," said Noyberg.
The stamps can be dipped in various colours of ink, either permanent or non-permanent so a new design can be added after each wash.
Ivan Noyberg and Gal Bulka recently graduated from Jerusalem's Bezalel Academy of Arts and Design.
