For interfacing there’s non-stretching tape which can be laid across the band, in overlapping pieces (yellow band or unconventional stuff like curtain band). Then there’s woven interfacing which can be something like sturdy cotton (twill) or something specifically used in jackets such as horse hair braid. I had never seen it. I like it!
What’s that in the background?
It’s my new pin cushion!
