I'm going to show you the basic techniques that I use when I'm sewing. You can go through the information here and practice it on a scrap of fabric, or go ahead and start any sewing project and come back here if you get stuck!
Step 1: General Sewing Terms.
Right side - This is the patterned side of the cloth, or the side that you want to show on the outside.
Wrong side - This is the back of the cloth, the un-patterned side, the side you don't want people to be able to see. Usually the wrong side of the fabric ends up on the inside of your sewing.
Seam - The line where the stitches hold two bits of cloth together.
