The Ripple hat has a texture at the first 3 inches of the hat. The texture is made from knitting welts.

A welt is a raised tube of material that is worked into a knitted piece. It runs along a line of stitches and resembles an i-cord.

Any DK yarn - two colours that meet the gauge of 22 sts = 4” will work for this. You can use two solid colours or one solid with a varigated as this sample demonstrates.

Hope you enjoy the hat.
