I’ve blogged about adding an i-cord edging to a bias edge, but that was only for one particular increasing sloped edge. Liz commented, “How would you decrease with the I-Cord on the bias?”
This raised a few questions for me: Is the angle the same for an increased edge and a decreased edge if the rate of change were the same, and would the number of compensating extra rows of i cord be different for different angles? Let’s Swatch and See.
My plan was to make a stockinette swatch, and an i-cord swatch; mark the i-cord with locking stitch markers at regular intervals, and lay it across my other swatch to see how many round of I-cord I need for each row, then make a third swatch with an angled edge and see if the prediction was correct.
My predictions are summarized below in this table. It’s a jpg, if this makes it hard for you to see it, please e-mail me and I’ll transcribe it in text.
The sample swatch did lay flat even before steam blocking, the increase and decrease edge both needed the same adjustments
I think on a next swatch, I might use slightly fewer short row i-cord rounds on an inside edge, and check my straight rows, they were the most wonky of all, but I never measured them to begin with, I should have known!
