Poplin is the fabric to learn on. It is a stable, closely woven cotton with a fine crosswise rib, it holds its shape, it presses beautifully and it does almost nothing unexpected.
Use a universal 80/12 with all-purpose polyester or cotton thread. Nothing special is required.
Stitch length 2.5 mm. Standard settings, standard tension.
Prewash it. Cotton poplin shrinks on the first wash, typically a few per cent, and shirts and dresses made from it get washed often. Wash and press before cutting.
Cut on grain and it stays where you put it. This is why patterns list poplin for beginners: it does not slide, stretch or distort, so the pieces you cut are the pieces you sew.
Finish the edges. It frays moderately — less than linen, more than a knit. Overlocking, zigzag, pinking or French seams all work; French and flat-felled seams suit shirts and are worth learning on a fabric this forgiving.
Press with a hot iron and steam. Poplin takes it, and crisp pressed seams and collar edges are what make a poplin shirt look bought rather than home-made.
Watch for stretch poplin. A version with a small percentage of elastane is now common. It sews like poplin but needs a slightly longer stitch and polyester thread with some give, and any waistband or opening should be stabilised.
Interface with a crisp fusible for collars, cuffs and plackets.
Questions people actually ask
Is poplin the same as broadcloth?
Effectively, in most shops. Both describe a fine plain weave with a subtle crosswise rib; the naming varies by region.
Why does my poplin shirt collar look limp?
Too soft an interfacing. Collars and cuffs want a crisp fusible, and the fabric will take it.
