co 8(16) with scrap yarn same color as main colors
co 8(16) with main skein
k to end both
k7 kfb - kfb k7
k2,cc,k5,cc,k2,kfb - kfb,k2,cc,k5,cc,k2
well, if you double knit, cast on 16 twice, and double all the other numbers. cc means change color.
I’ve written it up to the point where both cast ons are joined. From there it’s rather straightforward.
If the pattern is expanding to one side, increase (I used kfb (knit front and backloop) here, any other increase except yarn over would work) or cast on if necessary. If it’s going inward, decrease or cast off stitches.
For each “square” the shapes moves, decrease or increase one stitch on the end it is happening, orienting yourself on the chart.
Is that making it clearer?
