I answered your question in the other post you made, but I'll copy it here for you:
It sounds like you are using a chart
for the intarsia portion.
Your chart will have rows of symbols for the section you're working on. Just start on the bottom
row, and read the symbols from right to left
. Then, go up
to the next
row, and read the symbols left to right
. Keep going back and forth this way as you go up the chart. Soon, your knitting will match what you see on the chart, and it will get easier.
If your knitting is done with stockinette stitch, be sure the knit the rows on the right side, and purl the rows on the wrong side.
