The number and appearance of chromosomes in a cell is called a karyotype. A karyotype can only be seen and studied with a microscope. To make karyotypes easier to understand, karyograms are often made. In karyograms, homologous chromosomes are put side by side and then arranged by size.
A zigzag stitch is a great way to seam knit fabrics. Its inherent stretch allows for the fabric to stretch and move without fear of popping a seam. On light to medium weight knits, try using a stitch length of 1.5 and a width of 5. This setting closely mimics the look and function of an overlock stitch.
Aaron Marino of alpha m. discusses that knit ties are made with cotton, wool, and silk. They are not all created equal, namely with the weave. Look for a tight weave. The width varies too- look for anything over 2 inches for not too small or big. Alpha thinks this tie is too casual for suits; however, knit ties are acceptable with suits. It's great with a spread or point collar as well as Four in Hand knot because of the bulkier fabric.
