If the garment has buttonholes, stabilize the buttonhole area with a layer of interfacing. Use a fusible interfacing with lengthwise stability and crosswise stretch. Make vertical buttonholes, because they run parallel to the ribs in the knit and will be smoother and neater than horizontal buttonholes. Use vertical button holes that run parallel. Care for your knits.
Many lightweight knits are machine washable and dryable.
Some may require dry cleaning. Be sure to read the care label of the manufacturer when purchasing your fabric. To retain their shape, knits should be folded and placed in a drawer or on a shelf. If the knit garment is to hang, use a well padded hanger or fold in half and hang over the center rung of the hanger. Kenneth R.
