Question: what is the difference between 100 cotton and cotton poplin?
Answer: Poplin is a durable, lightweight cotton. It's not dissimilar to quilting cotton, though of a lighter heft and less prone to creasing. It has a tight weave, which in my experience can make it surprisingly tricky to sew with: it often seems to resist a needle. ... It's finer than poplin, with a crisp hand.
