Entrelac knitting is a very interesting type of knitting. It's started with a straight cast-on, then a row of triangles for a foundation. Then alternating rows, starting with an intial triangle, then rectangles, and ending with a row of triangles. It is most easily done with short rows - increasing rather than decreasing short rows. When finished, it almost looks like the tiers of blocks are woven. You can have many different colors for single pattern but to keep it simple try to use minimum color.
Here are six steps to make a entrelac scarf.
