The following are instructions on upholstering the seat of a crown-back parlour chair. These chairs are usually made with a loose seat frame, fastened together with dowels and upholstered on the top; the edges are not stitched, the flocks being strung on the edges with twine, this being tacked fast about every 4 in. to the top of the seat frame and then filled up with flocks. To make these chairs into spring seats, put a stuffing rail, 2 in. high, on the front and sides, web the bottom with four lines of chair webbing, stitch three chair springs to the web in the form of a triangle, the odd spring at the back. Cover the top over the springs with hessian and stitch the springs fast in an upright position. Pick on a layer of flocks and put on another cover of hessian; commence tacking in the centre of the chair front and work round to the back. Stay-tack the back, blind-stitch the front and sides, then stitch up the edge to a fine point with three rows of stitches. Pull out the stay-tacks, fill up hollow places with stuffing, pull the cover down as tight as possible, and secm-e; clean off the edges with a sharp knife; the stitching up makes no difference to the sweeps and curves, these being allowed for in tacking on the covers, letting out or taking up as may be necessary.
