I got up the courage to prepare and cut my sample steek this morning. I think it went well for a first time. Jared instructed us not to "go all precious" with our samples, so I tried hard not to. I do like things to look nice, though.
In these next three pictures you can see the line of single crochet on either side of the blue basting line. The crochet pulls the centre orange line of stitches open to expose the 'ladder' of stitches, both orange and beige, that will be cut. You remove the basting yarn before cutting.
And finally, the steek is cut, and if this were a cardigan I'd be ready to pick up stitches along each edge and knit a button band, or sew in a zipper.
And in this last shot I'll show off how pretty the back looks, because I now have good technique when working with two colours!
