Sewing question? Rib Knit Bias tape cut on grain or bias?
Have a sewing question for anyone, I am putting pink rib knit bias tape around the edges of a pink and white polka dot piece of fleece. My question is do I cut the rib knit on the bias which is not as stretchy or on straight grain which is very stretchy? I know when you make bias tape from woven cotton it is cut on the bias for the stretch, however rib knit is stretchy on the straight grain. So how do I this? I only have one piece of the pink rib knit as it was the leftovers.
