This mohochrome cube ornament is suitable for a bracelet, a belt, a bookmark. It will match any black-and-white office suit.
To weave it you'll need seed beads size 15, beading needle size 15 and fireline or fishing line with diameter 0.1 mm

Of course, you may use any other looming technique, or square stitch, or herringbone stitch.
The pattern includes a photo of the finished item, a brief description in a case if you use Easy looming without many ends of warp threads and 2 graphs.
the width is 3,6 cm, the length is as you wish
