"Corticelli, once upon a time, was the premier silk thread company. Corticelli silk was known around the world, and even now – though the company no longer exists – their threads are still well known by name."
Belding Corticelli has become the Couture sewers choice for thread tracing, its silky, thin fibers pull effortlessly from all fabrics, leaving no trace that they were even there.
Why thread trace?.... once your standard seam lines are removed from a muslin, you have to find a new way of transferring the sewing lines to your fashion fabric.
Thread tracing becomes a perfect semi-permanent solution. (These stitches will remain in your garment until its completion)
I like to use one colour initially to baste the muslin line and then as I alter or adjust a sew line after fittings etc I use different colours, so that I can easily remark my pattern and make a record of what I have done.
