beauty shotby



From time to time, every knitter needs to try something new. The Olof hat is a great project to learn Fair Isle technique. Fair Isle, also known as stranded colorwork knitting, is the perfect way to start experimenting with color and different pattern motifs. With a sport or DK weight yarn, solid color, tonal or gradient everyone can make colorful and warm winter garments.

The Olof hat is worked in the round from the bottom up, starting with two rows of 1x1 rib in contrasting color followed by two color 2x2 corrugated rib. The hat body uses 5 different, easy to remember Fair Isle motifs. They can be re-used in scarfs and mittens. The Olof hat is knitted in two colors. Would four colors work? Go ahead, try it.
