3. Chain Stitch: This is done side by side to fill large shapes or can be used to work single lines. Work the stitches towards you starting from the top of the line. Bring the thread out to the right side of fabric. Insert needle in fabric at the same point, holding the thread down with your left thumb. Bring the needle point out a short distance ahead and pull it through, keeping the working thread under the needle. The result is a loop. In starting the next stitch remember to insert the needle just inside the loop.

The manufacturing processes are listed in the accompanying chart, which indicates the two major differences in production. Triacetate is produced in both processes, but to make acetate, the solution is hydrolyzed (treated with water and aged) which causes some hydroxyl groups to reform. Triacetate is dissolved in a different solvent and acetate in a different solution.
