Trench coats are not only a great fashion statement, but also very functional. They protect against the rain, snow, or just cold weather. Trench coats stand apart from other coats by several factors; they have double buttons, a lapel, and a tie or belted waist. With the combination of these elements, the coat is distinctive.
Pick out the material you would like to use for your coat. If you would like to use a lining, pick out that material as well. Find matching buttons and thread.
Decide on the style of the coat you would like to do. While all trench coats have the same basic elements, there are a few stylish elements that can be incorporated such as length, if it will cut in at the waist, and how long the lapel will be. Pick out the pattern that goes with the style you would like to do.
Line up the pattern onto your material. Use the straight pins to secure the pattern in place on the material. Try to lay out the pattern so the least amount of scrap is left in between the pattern pieces. That way, if a mistake happens, you will have some extra material to use.
Cut the pattern out following the dashed lines. Be sure to cut allowing enough seam allowance for when you sew all the pieces together. The seam allowance is about ¼ to ½ inch.
Use the straight pins to connect the pattern pieces together, right sides facing each other. Sew the seams with a straight stitch on the sewing machine. The pattern will tell you in which order each piece should be sewn.
Sew the lining as a separate coat and then connect the two pieces together by resewing in the same seam in the major seams; the two side seams, back seam, and the fronts.
Sew on the buttons and belt loops. Fit the belt around the coat. Try it on to make sure everything matches up. Enjoy your new coat.
Be careful with all equipment. If you use a pattern fabric, be sure the pieces match up with lining the pieces together. Additional fabric may need to be purchased when using pattern fabric.
