Here's a little video I put together showing some of the increases and decreases I like to use in closed-loop cable knitting (this is a style of cable knitting that allows you to create near-horizontal bands of cables, and closed loops - hence the name!; it's very useful for knitting cables based on Celtic knotwork, like the cables in my hat pattern Tallorcen). Please note: There is no audio on this video - it's designed to be a supplement to the written instructions which are provided in the pattern. This is quite an old video, which I hope to update soon with audio commentary.
1-into-3 increases (stacked): at beginning of video
5-into-1 decrease: begins at 3m 43s
1-into-5 increase: begins at 5m 25s
