Here’s a great illustration of how your color choices in weaving these patterns can affect the design impact.
Basic zigzags are an easy way to start working in twill. The evenly-distributed floats make a thick, puffy fabric that is very protective. The pattern is reversible, slightly offset on the back, as you can see by the multi-tone potholder below.
The 27-peg pattern shown here can be easily cut down into an 18- or 9- peg pattern, by using the first 18 (or 9) rows and columns. (For the 9-peg pattern, place your loops every other peg of the 18-peg loom.)
