Anyway, maybe some similar shades would look nice. I may go and experiment . I used yarn holder eyelets 3 and 4 and just changed every two rows after programming in a design with the border. Of course, I had 20 needles on the left and 30 needles and did not center design so that is why you only see one side border.
Can you do a 2 color afghan with border on the Passap?
