Okay, so I was able to create the chart for the single color argyle scarf. But still have issues.
I want the diamonds to be defined by knit and purl sts only (garter and stockinette), no other st patterns, but I'm not sure if that will work. I want the parts of the diamonds in black to be done in stockinette, and the white backround to be done in garter. Now here is the problem: I want the outline diamonds in grey to be done in garter as well. But if I do both the background and outline diamonds in garter, the outlines will be lost, no? So what can I do so that the outline will stand out and not be lost among the garter background and not interfere with the black diamonds in St st?
