The potholders from the first and second photos are made with an acrylic yarn and measure approximately 17 cm x 13 cm.
The third and fourth photo one is made with a flat cotton yarn and measures 21 cm x 14 cm.
The pattern for these potholders is based on working each row with two color contrasting yarns using a special technique of slipped stitches together with knitted and purled stitches.
It is constructed first using straight knitting and finally the edge with circular knitting. It generates a stretchy, thick and reversible fabric.
The instructions are meticulously explained and supported with explicit photos to easy understand the process on making the work.
