Most t-shirts are made with knit fabric, but you may wish to choose a knit fabric with a fairly low amount of stretch to make the sewing process easier. As a general rule, though, it will be easiest to duplicate the fit of the original shirt you drafted your pattern from if you use a material similar in construction and weight. Wash and dry the material as you usually would before you do anything else with it. By washing the fabric first, you can pre-shrink it and set the dye. As a result, the pattern pieces you cut out and sew together should be more accurately sized. Fold the material in half and place your pattern pieces on top. Pin the pattern down, trace around it, and cut around each piece.  Fold the material in half with the right-sides facing in, and keep the fabric as flat as possible when you lay it out. Match the fold of the fabric to each "fold" mark on your pattern pieces. When pinning the pattern pieces in place, pin straight through both layers of material. Trace around the entire outline with fabric pencil, then cut along the outline without unpinning the pattern. After cutting out the material, you can unpin and remove the paper pattern pieces.
