High-quality cork is beautifully smooth and pliable. It's soft to the touch and has a stroke able softness. The fabric is made in such a way that it will retain these properties even after sewing. It does not dry, become brittle or flake with age. The character and drape are similar to that of leather/ rubber. Here are a few easy steps to sew them:
Stitch length = construction 3mm (generally)
Topstitch 3.5-4mm (the thicker the layers, the longer the stitch length.
Needle size = 80-90 (universal). You can use leather needles.
To secure your stitches, make a back-tack. In most prominent places try to secure your stitches by knotting the threads in the inside area.
Cork doesn't fray. But, always remember to conceal the edges because the backing might fray.
Cork does not crease, if you want folds, you will need to stitch them in. If you find a mild fold line you can safely iron it on a medium heat setting.
Cork can happily be sewn on home machines (max 3-4 layers).
Use rivets in case of bulkiness.
Use sewing clips/double-sided tape/glue to hold pattern pieces together, avoid using pins.
