4-way stretch (About 40 - 50% stretch on lengthwise grain). Soft drape with smooth handfeel
Slight degree of shine on face side
Use with nap cutting layout (i.e. all pattern pieces laid out in the same direction) so all pattern pieces reflect light the same way and shading is prevented
Crosswise stretch should go horizontally across the body
For cutting, lay out fabric on dressmaker's cutting board, hold down pattern pieces w/fabric weights and trace around pattern pieces with a sharp rotary cutter. This allows for more precise cutting with knit fabrics.
If cutting with shears, pin pattern pieces with thin, sharp pins (try our extra fine pins)
If interfacing is needed, use lightweight fusible knit interfacing
Use a ballpoint (stretch) needle when machine sewing
Use a knit stitch to maintain stretch - chainstitch is ideal, but you can also use overlock (serger) to sew seams without additional stitch
If you have to use a regular straight lockstitch, lower your stitch size (8-10 stitched per inch is a good estimate, but it’s best to experiment on a test swatch before sewing), and gently stretch the fabric while sewing to maintain stretch. Steam seams on lower (polyester/nylon) setting to eliminate unwanted puckering. You may want to use a pressing cloth if you have a particularly hot iron.
Use self-binding, overlock (serger) or a roll-back hem with coverstich for hems and edge
Wash cold on gentle cycle or hand wash in cold water, hang dry.
