Understanding Full Sewing Patterns
Full sewing patterns include all patterns that are not designated to be cut on fold. To identify a full pattern, take a look at the pattern's edges: if none of the edges are marked as cut-on-fold, you can assume that you are looking at a full pattern. Most patterns in dressmaking are considered full patterns and should include seam allowance along all edges.
When cutting full patterns, you may need a single, double or multiple cuts depending on the garment design. Your pattern should note how many pieces of the pattern you'll need. It is very common in dressmaking to have to cut two cuts of a full pattern. For that reason, the fabric can be folded so that the two identical pieces are cut simultaneously. The only difference between cutting a double cut full pattern and a cut on fold pattern is that the full pattern is not aligned with the fabric's edge the way a cut on fold pattern is.
Keep in mind that when pinning full patterns, the first thing that should be accurately aligned is the patterns grainline parallel to the selvage edge. The grainline, which is depicted by a double-pointed arrow on your sewing pattern, should be be aligned and pinned at an equal distance from the fabric's selvage such that the resulting garment pieces are perfectly on grain when cut.
