Bamboo reminds us of tall erect stalks, and this version of the double knit rib looks very similar. A very pretty design for most anything worked with even number of stitches. The wide ribs are formed with 4 stitches in a series, but when opened, you will see lacy opening in center, between the 4 stitches.
Since this is a single pass of the loom, we will show illustration of 1st 10 stitches with row #1 and then, the 2nd illustration is row #2.
Row #1: 1 2 3 4 5 6 7 8 9 10
Row #2: 1 2 3 4 5 6 7 8 9 10
The minimum number of stitches to create this pattern would be 6 sts. After that, add 4 more, so you can do it with 10 sts or 14 sts, 18 sts, or 22 sts, and on. The reason for this is each row starts with either the 2 single wraps or the double wrap and it needs to end with same wrap. You can see that the first 2 sts are back/to/back wraps. The next 2 sts create a square or double wrap. You keep alternating the 2 stitch series, and end with the series same as you began the row. The next row or row #2, will start and end with the opposite series.
Look at the illustration and see the row #1 weave, the pegs 1 & 2 are single, pegs 3 & 4 are a double, pegs 5 & 6 are single, and 7 & 8 are a double, and 9 & 10 are single.
The row #2 will start with pegs 1 & 2 double, pegs 3 & 4 single, pegs 5 & 6 double, pegs 7 & 8 single, pegs 9 & 10 are double. Once you do this a few rows, you will get comfortable with it and see your pretty design emerge.
How do you look at the completed row and know for sure which series you have just completed? If you look at the illustration carefully, you will notice that with row 1, the yarn ends at peg #10. That means that you just completed the 2 single pegs, so you want to start the next row with the double pegs.
If you look at row #2, you see that you end with the yarn coming from peg #9, so you just completed the double sts and will start the next row with 2 single sts.
Cast On in pattern(sample), or with stockinette, using row #1 as first row of pattern. We will show only the first 10 sts.
Row #1: Weave around peg #1 top, down to peg #1 bottom, up to peg #2 top, and down to peg #2 bottom. Weave the next 4 pegs per the diagram. Then next 2 consecutive, and continue across loom.
You are ready to hook over. Repeat row#1 and hook over. Repeat row #2, and hook over.
