I want to knit a throw where I have maybe 20 colours, with a new colour every row. I don’t want fringes. I was wondering if best strategy might be to plan hems each side with the colour changes tucked inside. And if so, would knitting a column of purl an inch in from the edges make something that would turn and sit nicely for the hem, the way one might do that for a hem at the bottom of a garment.
I know I should do a swatch, but I doubt that it will behave the same way as a 6’ x 6’ blanket. And so far I haven’t found anything online that discusses this.
