Huck weaving is also known as Swedish weaving, huck embroidery, or huckaback darning and there is a Portuguese variation known as "oitinho".
It was very popular in the US during the 1930s and 1940s, when it was often taught in schools.
Huck weaving is a type of surface darning that utilizes only two stitches. The thread colors can be different or similar to the base fabric color and the resulting design will look complex or simple, depending on the colors used and the number of stitched lines in the design.
