Well, you would have thought I had never knit lace as many times as I knit, unknit, reknit this project. Never the less, part 1 done. The green-yellow stripes will come out. They are what are called "life lines." When knitting a pattern with yarn over's and combination stitches, a defensive move is to periodically run waste yarn through a row of stitches that ends a section which contains no errors. Then, should one have to rip out, you can safely rip back to a place that has no errors and also maintain the integrity of the stitches and pattern.
